Combining 4 textures in 1

Hello community. I’m bad at UV Mapping and I need to combine all the 4 textures from a model to 1 but I don’t know how to do that. I know it’s possible in 3DS Max and I’m wondering if same is possible in Blender. I could find a way by combining all the textures in an image editor and modifying the UV Map in Blender according to the new texture but this is a very slow and approximate process. I tried to use the “Baking” option in the rendering settings but it did nothing good as they are all overlapping each other. Is there a way to tidy this while keeping a good placement of the texture?:


Or is there a way I can “Bake” a new texture from the existing one directly in Blender?
I really don’t know and am totally lost about what and how to do. Searching on Internet didn’t help me at all.

Thanks in advance.

explicitly set the uvmaps for each of your textures, create a new uvmap for the final (composited) texture without overlapping, set this new uvmap as defaultand bake the color information.
in the end you can replace the initial textures with the baked one, and remove the unused uvmaps.

Thanks a lot. At first I couldn’t understand the process but by reading again and again I succeeded at making the new texture.
This thread is now solved.
