7// indexing into the appropriate binding array. For example, to access the base
8// color texture of a `StandardMaterial` in bindless mode, write
9// `bindless_textures_2d[materials[slot].base_color_texture]`, where
10// `materials` is the bindless index table and `slot` is the index into that
11// table (which can be found in the `Mesh`).
