Optionally, a viewport can have its own 2D or 3D world, so it doesn't share what it draws with other viewports.
Viewports can also choose to be audio listeners, so they generate positional audio depending on a 2D or 3D camera child of it.
Also, viewports can be assigned to different screens in case the devices have multiple screens.
Finally, viewports can also behave as render targets, in which case they will not be visible unless the associated texture is used to draw.

SCALING_3D_MODE_MAX:null = 5
Represents the size of the Scaling3DMode enum.
MSAA_DISABLED:null = 0
Multisample antialiasing mode disabled. This is the default value, and is also the fastest setting.
MSAA_2X:null = 1
Use 2× Multisample Antialiasing. This has a moderate performance cost. It helps reduce aliasing noticeably, but 4× MSAA still looks substantially better.
MSAA_4X:null = 2
Use 4× Multisample Antialiasing. This has a significant performance cost, and is generally a good compromise between performance and quality.
MSAA_8X:null = 3

Objects are displayed normally.
DEBUG_DRAW_UNSHADED:null = 1
Objects are displayed without light information.
DEBUG_DRAW_LIGHTING:null = 2
Objects are displayed without textures and only with lighting information.
Note: When using this debug draw mode, custom shaders are ignored since all materials in the scene temporarily use a debug material. This means the result from custom shader functions (such as vertex displacement) won't be visible anymore when using this debug draw mode.
DEBUG_DRAW_OVERDRAW:null = 3
Objects are displayed semi-transparent with additive blending so you can see where they are drawing over top of one another. A higher overdraw means you are wasting performance on drawing pixels that are being hidden behind others.
Note: When using this debug draw mode, custom shaders are ignored since all materials in the scene temporarily use a debug material. This means the result from custom shader functions (such as vertex displacement) won't be visible anymore when using this debug draw mode.

DEBUG_DRAW_PSSM_SPLITS:null = 14
Colors each PSSM split for the DirectionalLight3Ds in the scene a different color so you can see where the splits are. In order (from closest to furthest from the camera), they are colored red, green, blue, and yellow.
Note: When using this debug draw mode, custom shaders are ignored since all materials in the scene temporarily use a debug material. This means the result from custom shader functions (such as vertex displacement) won't be visible anymore when using this debug draw mode.
Note: Only supported when using the Forward+ or Mobile rendering methods.
DEBUG_DRAW_DECAL_ATLAS:null = 15
Draws the decal atlas used by Decals and light projector textures in the upper left quadrant of the Viewport.

Note: Only supported when using the Forward+ or Mobile rendering methods.
DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_NEAREST:null = 0
The texture filter reads from the nearest pixel only. This makes the texture look pixelated from up close, and grainy from a distance (due to mipmaps not being sampled).
DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_LINEAR:null = 1
The texture filter blends between the nearest 4 pixels. This makes the texture look smooth from up close, and grainy from a distance (due to mipmaps not being sampled).
DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_LINEAR_WITH_MIPMAPS:null = 2
The texture filter blends between the nearest 4 pixels and between the nearest 2 mipmaps (or uses the nearest mipmap if [member ProjectSettings.rendering/textures/default_filters/use_nearest_mipmap_filter] is
Use this for non-pixel art textures that may be viewed at a low scale (e.g. due to Camera2D zoom or sprite scaling), as mipmaps are important to smooth out pixels that are smaller than on-screen pixels.
DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_NEAREST_WITH_MIPMAPS:null = 3
The texture filter reads from the nearest pixel and blends between the nearest 2 mipmaps (or uses the nearest mipmap if [member ProjectSettings.rendering/textures/default_filters/use_nearest_mipmap_filter] is
Use this for non-pixel art textures that may be viewed at a low scale (e.g. due to Camera2D zoom or sprite scaling), as mipmaps are important to smooth out pixels that are smaller than on-screen pixels.
DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_MAX:null = 4
Represents the size of the DefaultCanvasItemTextureFilter enum.
DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_DISABLED:null = 0
Disables textures repeating. Instead, when reading UVs outside the 0-1 range, the value will be clamped to the edge of the texture, resulting in a stretched out look at the borders of the texture.
DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_ENABLED:null = 1
Enables the texture to repeat when UV coordinates are outside the 0-1 range. If using one of the linear filtering modes, this can result in artifacts at the edges of a texture when the sampler filters across the edges of the texture.
DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_MIRROR:null = 2
Flip the texture when repeating so that the edge lines up instead of abruptly changing.
DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_MAX:null = 3

The input texture for variable rate shading will be processed each frame.
VRS_UPDATE_MAX:null = 3
Represents the size of the VRSUpdateMode enum.
Emitted when a Control node grabs keyboard focus.
Note: A Control node losing focus doesn't cause this signal to be emitted.
Emitted when the size of the viewport is changed, whether by resizing of window, or some other means.
Sets the maximum number of samples to take when using anisotropic filtering on textures (as a power of two). A higher sample count will result in sharper textures at oblique angles, but is more expensive to compute. A value of 0 forcibly disables anisotropic filtering, even on materials where it is enabled.
The anisotropic filtering level also affects decals and light projectors if they are configured to use anisotropic filtering. See [member ProjectSettings.rendering/textures/decals/filter] and [member ProjectSettings.rendering/textures/light_projectors/filter].
Note: In 3D, for this setting to have an effect, set [member BaseMaterial3D.texture_filter] to [constant BaseMaterial3D.TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC] or [constant BaseMaterial3D.TEXTURE_FILTER_NEAREST_WITH_MIPMAPS_ANISOTROPIC] on materials.
Note: In 2D, for this setting to have an effect, set [member CanvasItem.texture_filter] to [constant CanvasItem.TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC] or [constant CanvasItem.TEXTURE_FILTER_NEAREST_WITH_MIPMAPS_ANISOTROPIC] on the CanvasItem node displaying the texture (or in CanvasTexture). However, anisotropic filtering is rarely useful in 2D, so only enable it for textures in 2D if it makes a meaningful visual difference.
If true , the viewport will process 2D audio streams.
If true , the viewport will process 3D audio streams.
The rendering layers in which this Viewport renders CanvasItem nodes.
Sets the default filter mode used by CanvasItems in this Viewport.

The overlay mode for test rendered geometry in debug purposes.
Disable 3D rendering (but keep 2D rendering).
Determines how sharp the upscaled image will be when using the FSR upscaling mode. Sharpness halves with every whole number. Values go from 0.0 (sharpest) to 2.0. Values above 2.0 won't make a visible difference.
To control this property on the root viewport, set the [member ProjectSettings.rendering/scaling_3d/fsr_sharpness] project setting.
The global canvas transform of the viewport. The canvas transform is relative to this.
If true , the viewport will not receive input events.
If true , sub-windows (popups and dialogs) will be embedded inside application window as control-like nodes. If false , they will appear as separate windows handled by the operating system.
If true , the GUI controls on the viewport will lay pixel perfectly.
If true , this viewport will mark incoming input events as handled by itself. If false , this is instead done by the first parent viewport that is set to handle input locally.
A SubViewportContainer will automatically set this property to
See also set_input_as_handled and is_input_handled.
The automatic LOD bias to use for meshes rendered within the Viewport (this is analogous to [member ReflectionProbe.mesh_lod_threshold]). Higher values will use less detailed versions of meshes that have LOD variations generated. If set to 0.0 , automatic LOD is disabled. Increase mesh_lod_threshold to improve performance at the cost of geometry detail.
To control this property on the root viewport, set the [member ProjectSettings.rendering/mesh_lod/lod_change/threshold_pixels] project setting.
Note: mesh_lod_threshold does not affect GeometryInstance3D visibility ranges (also known as "manual" LOD or hierarchical LOD).
The multisample antialiasing mode for 2D/Canvas rendering. A higher number results in smoother edges at the cost of significantly worse performance. A value of [constant Viewport.MSAA_2X] or [constant Viewport.MSAA_4X] is best unless targeting very high-end systems. This has no effect on shader-induced aliasing or texture aliasing.
See also [member ProjectSettings.rendering/anti_aliasing/quality/msaa_2d] and [method RenderingServer.viewport_set_msaa_2d].
The multisample antialiasing mode for 3D rendering. A higher number results in smoother edges at the cost of significantly worse performance. A value of [constant Viewport.MSAA_2X] or [constant Viewport.MSAA_4X] is best unless targeting very high-end systems. See also bilinear scaling 3D scaling_3d_mode for supersampling, which provides higher quality but is much more expensive. This has no effect on shader-induced aliasing or texture aliasing.
See also [member ProjectSettings.rendering/anti_aliasing/quality/msaa_3d] and [method RenderingServer.viewport_set_msaa_3d].
If true and one of the following conditions are true: [member SubViewport.size_2d_override_stretch] and [member SubViewport.size_2d_override] are set, [member Window.content_scale_factor] is set and scaling is enabled, oversampling_override is set, font and DPITexture oversampling are enabled.
If greater than zero, this value is used as the font oversampling factor, otherwise oversampling is equal to viewport scale.
If true , the objects rendered by viewport become subjects of mouse picking process.
Note: The number of simultaneously pickable objects is limited to 64 and they are selected in a non-deterministic order, which can be different in each picking process.
If true , the input_event signal will only be sent to one physics object in the mouse picking process. If you want to get the top object only, you must also enable physics_object_picking_sort.
If
This applies to 2D CanvasItem object picking only.
If true , objects receive mouse picking events sorted primarily by their [member CanvasItem.z_index] and secondarily by their position in the scene tree. If false , the order is undetermined.
Note: This setting is disabled by default because of its potential expensive computational cost.
Note: Sorting happens after selecting the pickable objects. Because of the limitation of 64 simultaneously pickable objects, it is not guaranteed that the object with the highest [member CanvasItem.z_index] receives the picking event.
Use 16 bits for the omni/spot shadow depth map. Enabling this results in shadows having less precision and may result in shadow acne, but can lead to performance improvements on some devices.
The subdivision amount of the first quadrant on the shadow atlas.
The subdivision amount of the second quadrant on the shadow atlas.
The subdivision amount of the third quadrant on the shadow atlas.
The subdivision amount of the fourth quadrant on the shadow atlas.
The shadow atlas' resolution (used for omni and spot lights). The value is rounded up to the nearest power of 2.
Note: If this is set to
Sets scaling 3D mode. Bilinear scaling renders at different resolution to either undersample or supersample the viewport. FidelityFX Super Resolution 1.0, abbreviated to FSR, is an upscaling technology that produces high quality images at fast framerates by using a spatially aware upscaling algorithm. FSR is slightly more expensive than bilinear, but it produces significantly higher image quality. FSR should be used where possible.
To control this property on the root viewport, set the [member ProjectSettings.rendering/scaling_3d/mode] project setting.
Scales the 3D render buffer based on the viewport size uses an image filter specified in [member ProjectSettings.rendering/scaling_3d/mode] to scale the output image to the full viewport size. Values lower than 1.0 can be used to speed up 3D rendering at the cost of quality (undersampling). Values greater than 1.0 are only valid for bilinear mode and can be used to improve 3D rendering quality at a high performance cost (supersampling). See also [member ProjectSettings.rendering/anti_aliasing/quality/msaa_3d] for multi-sample antialiasing, which is significantly cheaper but only smooths the edges of polygons.
When using FSR upscaling, AMD recommends exposing the following values as preset options to users "Ultra Quality: 0.77", "Quality: 0.67", "Balanced: 0.59", "Performance: 0.5" instead of exposing the entire scale.
To control this property on the root viewport, set the [member ProjectSettings.rendering/scaling_3d/scale] project setting.
Sets the screen-space antialiasing method used. Screen-space antialiasing works by selectively blurring edges in a post-process shader. It differs from MSAA which takes multiple coverage samples while rendering objects. Screen-space AA methods are typically faster than MSAA and will smooth out specular aliasing, but tend to make scenes appear blurry.
See also [member ProjectSettings.rendering/anti_aliasing/quality/screen_space_aa] and [method RenderingServer.viewport_set_screen_space_aa].
Controls how much of the original viewport's size should be covered by the 2D signed distance field. This SDF can be sampled in CanvasItem shaders and is also used for GPUParticles2D collision. Higher values allow portions of occluders located outside the viewport to still be taken into account in the generated signed distance field, at the cost of performance. If you notice particles falling through LightOccluder2Ds as the occluders leave the viewport, increase this setting.
The percentage is added on each axis and on both sides. For example, with the default SDF_OVERSIZE_120_PERCENT, the signed distance field will cover 20% of the viewport's size outside the viewport on each side (top, right, bottom, left).
The resolution scale to use for the 2D signed distance field. Higher values lead to a more precise and more stable signed distance field as the camera moves, at the cost of performance.
If true , CanvasItem nodes will internally snap to full pixels. Their position can still be sub-pixel, but the decimals will not have effect. This can lead to a crisper appearance at the cost of less smooth movement, especially when Camera2D smoothing is enabled.
If true , vertices of CanvasItem nodes will snap to full pixels. Only affects the final vertex positions, not the transforms. This can lead to a crisper appearance at the cost of less smooth movement, especially when Camera2D smoothing is enabled.
Affects the final texture sharpness by reading from a lower or higher mipmap (also called "texture LOD bias"). Negative values make mipmapped textures sharper but grainier when viewed at a distance, while positive values make mipmapped textures blurrier (even when up close).
Enabling temporal antialiasing (use_taa) will automatically apply a
Note: If scaling_3d_scale is lower than
To control this property on the root viewport, set the [member ProjectSettings.rendering/textures/default_filters/texture_mipmap_bias] project setting.
If true , the viewport should render its background as transparent.
Note: Due to technical limitations, certain rendering features are disabled when a viewport has a transparent background. This currently applies to screen-space reflections, subsurface scattering, and depth of field.
When using the Mobile or Forward+ renderers, set use_debanding to enable or disable the debanding feature of this Viewport. If use_hdr_2d is false , 2D rendering is not affected by debanding unless the [member Environment.background_mode] is [constant Environment.BG_CANVAS]. If use_hdr_2d is true , debanding will only be applied if this is the root Viewport and will affect all 2D and 3D rendering, including canvas items.
use_debanding has no effect when using the Compatibility rendering method. The Mobile renderer can also use material debanding, which can be set with [method RenderingServer.material_set_use_debanding] or configured with [member ProjectSettings.rendering/anti_aliasing/quality/use_debanding].
See also [member ProjectSettings.rendering/anti_aliasing/quality/use_debanding], [method RenderingServer.material_set_use_debanding], and [method RenderingServer.viewport_set_use_debanding].
If true , 2D rendering will use a high dynamic range (HDR) format framebuffer matching the bit depth of the 3D framebuffer. When using the Forward+ or Compatibility renderer, this will be an RGBA16 framebuffer. When using the Mobile renderer, it will be an RGB10_A2 framebuffer.
Additionally, 2D rendering will be performed on linear values and will be converted using the appropriate transfer function immediately before blitting to the screen (if the Viewport is attached to the screen).
Practically speaking, this means that the end result of the Viewport will not be clamped to the
If true , OccluderInstance3D nodes will be usable for occlusion culling in 3D for this viewport. For the root viewport, [member ProjectSettings.rendering/occlusion_culling/use_occlusion_culling] must be set to true instead.
Note: Enabling occlusion culling has a cost on the CPU. Only enable occlusion culling if you actually plan to use it, and think whether your scene can actually benefit from occlusion culling. Large, open scenes with few or no objects blocking the view will generally not benefit much from occlusion culling. Large open scenes generally benefit more from mesh LOD and visibility ranges ([member GeometryInstance3D.visibility_range_begin] and [member GeometryInstance3D.visibility_range_end]) compared to occlusion culling.
Note: Due to memory constraints, occlusion culling is not supported by default in Web export templates. It can be enabled by compiling custom Web export templates with
Enables temporal antialiasing for this viewport. TAA works by jittering the camera and accumulating the images of the last rendered frames, motion vector rendering is used to account for camera and object motion.
Note: The implementation is not complete yet, some visual instances such as particles and skinned meshes may show artifacts.
See also [member ProjectSettings.rendering/anti_aliasing/quality/use_taa] and [method RenderingServer.viewport_set_use_taa].
If true , the viewport will use the primary XR interface to render XR output. When applicable this can result in a stereoscopic image and the resulting render being output to a headset.
The Variable Rate Shading (VRS) mode that is used for this viewport. Note, if hardware does not support VRS this property is ignored.
Texture to use when vrs_mode is set to [constant Viewport.VRS_TEXTURE].
The texture must use a lossless compression format so that colors can be matched precisely. The following VRS densities are mapped to various colors, with brighter colors representing a lower level of shading precision:

Sets the update mode for Variable Rate Shading (VRS) for the viewport. VRS requires the input texture to be converted to the format usable by the VRS method supported by the hardware. The update mode defines how often this happens. If the GPU does not support VRS, or VRS is not enabled, this property is ignored.
The custom World2D which can be used as 2D environment source.
The custom World3D which can be used as 3D environment source.
Returns the currently active 2D audio listener. Returns null if there are no active 2D audio listeners, in which case the active 2D camera will be treated as listener.
Returns the currently active 3D audio listener. Returns null if there are no active 3D audio listeners, in which case the active 3D camera will be treated as listener.
Returns the currently active 2D camera. Returns null if there are no active cameras.
Note: If called while the Camera Override system is active in editor, this will return the internally managed override camera. It is therefore advised to avoid caching the return value, or to check that the cached value is still a valid instance and is the current camera before use. See [method @GlobalScope.is_instance_valid] and [method Camera2D.is_current].

Returns an individual bit on the rendering layer mask.
Returns a list of the visible embedded Windows inside the viewport.
Returns the transform from the viewport's coordinate system to the embedder's coordinate system.
Returns viewport oversampling factor.
Returns the positional shadow atlas quadrant subdivision of the specified quadrant.
Returns rendering statistics of the given type.
Returns the transform from the Viewport's coordinates to the screen coordinates of the containing window manager window.
Returns the automatically computed 2D stretch transform, taking the Viewport's stretch settings into account. The final value is multiplied by [member Window.content_scale_factor], but only for the root viewport. If this method is called on a SubViewport (e.g., in a scene tree with SubViewportContainer and SubViewport), the scale factor of the root window will not be applied. Using [method Transform2D.get_scale] on the returned value, this can be used to compensate for scaling when zooming a Camera2D node, or to scale down a TextureRect to be pixel-perfect regardless of the automatically computed scale factor.
Note: Due to how pixel scaling works, the returned transform's X and Y scale may differ slightly, even when [member Window.content_scale_aspect] is set to a mode that preserves the pixels' aspect ratio. If [member Window.content_scale_aspect] is [constant Window.CONTENT_SCALE_ASPECT_IGNORE], the X and Y scale may differ significantly.
Returns the viewport's texture.
Note: When trying to store the current texture (e.g. in a file), it might be completely black or outdated if used too early, especially when used in e.g. [method Node._ready]. To make sure the texture you get is correct, you can await [signal RenderingServer.frame_post_draw] signal.
Note: When use_hdr_2d is
Returns the viewport's RID from the RenderingServer.
Returns the visible rectangle in global screen coordinates.
Cancels the drag operation that was previously started through [method Control._get_drag_data] or forced with [method Control.force_drag].
Returns the drag data from the GUI, that was previously returned by [method Control._get_drag_data].
Returns the drag data human-readable description.
Typically the leaf Control node or deepest level of the subtree which claims hover. This is very useful when used together with [method Node.is_ancestor_of] to find if the mouse is within a control tree.
Returns true if the drag operation is successful.
Returns true if a drag operation is currently ongoing and where the drop action could happen in this viewport.
Alternative to [constant Node.NOTIFICATION_DRAG_BEGIN] and [constant Node.NOTIFICATION_DRAG_END] when you prefer polling the value.
Sets the drag data human-readable description.
Returns whether the current InputEvent has been handled. Input events are not handled until set_input_as_handled has been called during the lifetime of an InputEvent.
This is usually done as part of input handling methods like [method Node._input], [method Control._gui_input] or others, as well as in corresponding signal handlers.
If handle_input_locally is set to
Inform the Viewport that the mouse has entered its area. Use this function before sending an InputEventMouseButton or InputEventMouseMotion to the Viewport with [method Viewport.push_input]. See also notify_mouse_exited.
Note: In most cases, it is not necessary to call this function because SubViewport nodes that are children of SubViewportContainer are notified automatically. This is only necessary when interacting with viewports in non-default ways, for example as textures in TextureRect or with an Area3D that forwards input events.
Inform the Viewport that the mouse has left its area. Use this function when the node that displays the viewport notices the mouse has left the area of the displayed viewport. See also notify_mouse_entered.
Note: In most cases, it is not necessary to call this function because SubViewport nodes that are children of SubViewportContainer are notified automatically. This is only necessary when interacting with viewports in non-default ways, for example as textures in TextureRect or with an Area3D that forwards input events.
Triggers the given event in this Viewport. This can be used to pass an InputEvent between viewports, or to locally apply inputs that were sent over the network or saved to a file.
If in_local_coords is
While this method serves a similar purpose as [method Input.parse_input_event], it does not remap the specified event based on project settings like [member ProjectSettings.input_devices/pointing/emulate_touch_from_mouse].
Calling this method will propagate calls to child nodes for following methods in the given order:
- [method Node._input]
- [method Control._gui_input] for Control nodes
- [method Node._shortcut_input]
- [method Node._unhandled_key_input]
- [method Node._unhandled_input]
If an earlier method marks the input as handled via set_input_as_handled, any later method in this list will not be called.
If none of the methods handle the event and physics_object_picking is

Note: This method doesn't propagate input events to embedded Windows or SubViewports.
Set/clear individual bits on the rendering layer mask. This simplifies editing this Viewport's layers.
Stops the input from propagating further up the SceneTree.
Sets the number of subdivisions to use in the specified quadrant. A higher number of subdivisions allows you to have more shadows in the scene at once, but reduces the quality of the shadows. A good practice is to have quadrants with a varying number of subdivisions and to have as few subdivisions as possible.
Force instantly updating the display based on the current mouse cursor position. This includes updating the mouse cursor shape and sending necessary [signal Control.mouse_entered], [signal CollisionObject2D.mouse_entered], [signal CollisionObject3D.mouse_entered] and [signal Window.mouse_entered] signals and their respective mouse_exited counterparts.
Note: warp_mouse is only supported on Windows, macOS and Linux. It has no effect on Android, iOS and Web.
