Combine several textures into one This might have been answered before, but my problem is a little bit more complicated. I'm porting some WW2 warship models and they have lots of different small models like cranes, anchors, lifeboats and whatnot. Each one of those models has its own material, making it absurdly complicated to export them all as textures one by one.

This is the problem I'm currently facing, as you can see on the right there are dozens of individual materials, and my goal is to join them all into a single one if possible so I don't have to export them one by one:
I think that if you want to keep the quality of the textures maybe you need to make 4 or 5 materials, or a very large texture for all. For one material you need to join a couple of meshes, make a "Lightmap Pack" unwrap and then a bake of the textures, that way you'll have a single texture for all the meshes you have joined
