UncompressedVertex

#

Most of these attributes are not used in the default prepass fragment shader, but they are still needed so we can pass them to custom prepass shaders like pbr_prepass.wesl.

Functions

decompress_vertex

#

The instance_index parameter must match vertex_in.instance_index. This is a work around for a wgpu dx12 bug. See https://github.com/gfx-rs/naga/issues/2416

fn decompress_vertex (
vertex_in: Vertex
, 
instance_index: u32
) -> UncompressedVertex
