pub const MESH_GROUP: u32 = 2;Expand description
Bind-group index of the mesh group.
The built-in lit variants bind nothing here: every input they read is in
the global group or on the instance stream. The index stays a general
extension point, so a caller’s own pipeline can bind per-mesh data — a tint,
a transform palette, a material parameter — and
crate::scene::DrawEntry will bind it.
