Thin Instance UV offset per instance

[Evgeni_Popov]

Here are some examples:

Thin Instanced squares or triangles sharing the same projection texture?

You can try to add an offset to the coordinate textures, as in: Or:

Mesh instances with different UVs not working

Yes, in that case you should use a single texture atlas and pass the (u,v) offset into this texture to your instance. That’s basically what the PG you linked does (https://www.babylonjs-playground.com/#64K1I1#2).
