WHAT IS GRASS? Grass can be seen in multiple ways in video games: It can be a texture on the ground, it can be one or multiple flat cards on top on the ground or even billboards that rotate towards the camera. It can also be real geometry where each blade is rendered with one or more triangles. It actually belongs to the category of foliage but has a special role, because it can cover huge areas with a lot of entities.

WHAT IS FOLIAGE? Foliage is similar to high grass, which can also be either cards, real complex geometry of lots of triangles or a mix. The foliage category can include a wide variety of asset types, but they mostly serve as details on top of terrains and landscape or to support trees, walls and similar structures.

PROCEDURAL GRASS PATCHES The Rokojori Action Library contains a GrassPatch node, which generates grass patch models. It allows a lot of customization like triangle size, width, height, bending, rolling, placing, LODs and a lot of more. If you want quickly to create grass patches, this could be the right tool. Combined with a MultiBaker using a FlatBaker cards can be baked directly in Godot. There are also free baked grass assets, created with those tools in the store.

FOLIAGE RENDERER To render grass and foliage the FoliageRenderer can be used. It has a lot features to render multiple layers of grass and foliage type. It creates automatically materials that can fade and adapt to terrain/height maps.
