I have a scene in Unity, a map, where all the models are placed correctly already. The problem is, that the memory is already overloaded, and many props have their own textures. I want to make a 4k atlases and pack 10-15 models' textures in each atlas respectively.
I was trying to use MA Atlas Packer, but the problem is, that it adjusts the UV map of each model, and create a separate version of each asset for use with texture atlas, obviously. Is there a more correct way of making atlases, when you already have a complete map, without the need of replacing the initial models with adjusted new ones?
