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.

current_skin_index: u32

The current skin index, or u32::MAX if there’s no skin.

material_and_lightmap_bind_group_slot: u32

The material and lightmap indices, packed into 32 bits.

Low 16 bits: index of the material inside the bind group data. High 16 bits: index of the lightmap in the binding array.

tag: u32

User supplied tag to identify this mesh instance.

pad: u32

Padding.
