Holds a particle configuration for GPUParticles2D or GPUParticles3D nodes.

ParticleProcessMaterial defines particle properties and behavior. It is used in the process_material of the GPUParticles2D and GPUParticles3D nodes. Some of this material's properties are applied to each particle when emitted, while others can have a CurveTexture or a GradientTexture1D applied to vary numerical or color values over the lifetime of the particle.

Emitted when this material's emission shape is changed in any way. This includes changes to emission_shape, emission_shape_scale, or emission_sphere_radius, and any other property that affects the emission shape's offset, size, scale, or orientation.

Note: This signal is only emitted inside the editor for performance reasons.
