I just noticed that thin instances don’t work on ShaderMaterial but work on StandardMaterial, I don’t quite know all about thin instances but does anyone know how to make it work on ShaderMaterial? I believe it has something to do with the attributes.

You need to add some includes in your shader to support instances / thin instances:

@Evgeni_Popov Just one quick question, is it possible to use thin instance buffers with both translation and rotation or is only one the limit? because the docs say “position/rotation/scaling.”

Yes, you can have a position + rotation + scaling: you must give a matrix to create a thin instance, and a matrix can hold at the same time a position + a rotation + a scaling.
