Im trying to improve performance, and I found an asset called https://forum.unity.com/threads/one-batch-combine-hundreds-of-materials-into-one-draw-call.555643/ that claims to do what I need - which is reducing many material maps across multiple objects to 1 material.
These are baked maps from blender, and Im using just a standard shader with albedo and emission really. OneBatch does not work, and I need to know within unity (or blender really) if theres a way to easily pack these maps into 1 file and/or material, without screwing up the existent UV unwrapping.
All the maps are the same size, and there are 1-3 per object (different sub meshes). What are some solutions?
