Base class for all primitive meshes. Handles applying a [Material] to a primitive mesh. Examples include [BoxMesh], [CapsuleMesh], [CylinderMesh], [PlaneMesh], [PrismMesh], and [SphereMesh].
Returns mesh arrays used to constitute surface of [Mesh]. The result can be passed to [method ArrayMesh.add_surface_from_arrays] to create a new surface. For example:
Overrides the [AABB] with one defined by user for use with frustum culling. Especially useful to avoid unexpected culling when using a shader to offset vertices.
If [member add_uv2] is set, specifies the padding in pixels applied along seams of the mesh. Lower padding values allow making better use of the lightmap texture (resulting in higher texel density), but may introduce visible lightmap bleeding along edges.
If the size of the lightmap texture can't be determined when generating the mesh, UV2 is calculated assuming a texture size of 1024x1024.
