Fields

world_from_local: [Vec4; 3]

previous_world_from_local: [Vec4; 3]

local_from_world_transpose_a: [Vec4; 2]

local_from_world_transpose_b: f32

flags: u32

lightmap_uv_rect: UVec2

first_vertex_index: u32

The index of this mesh’s first vertex in the vertex buffer.

Multiple meshes can be packed into a single vertex buffer (see MeshAllocator). This value stores the offset of the first vertex in this mesh in that buffer.

pad_a: u32

Padding.

pad_b: u32

Padding.

pad_c: u32

Padding.
