Hi @sarahlenker ! Thank you for answering!
I asked because I’m trying to reduce txt sampling and draw calls, I’m doining it trought a unique master material to instance dynamically, this material I made adapts itself to any mesh using mat functions. In this case, I’m talking about architect mesh, so they’re not so big but not so small also, so I tought 2k for their txts was better. My idea was to create atlases with trim sheets I made in Blender because I’m generating a procedural map. So, If I got properly what you said , in this my case, it’s better for me to have separated textures ? Because I’ve few txts but high res. Right?
