I've scanned a little statue and made it into a 3D object using Meshroom. Because the software creates the textures from the images you provide, some of them are too big, and it splits them in 2 or more parts.
I've edited the model in Blender, and I cleaned the object to the point that only 1/4 of the initial textures are used and exported it as an obj. When I wanted to upload my object to sketchfab, I found out I can only select one of the two textures to apply it on the model.
When searching for a fix I have found some similar posts that pointed that baking the textures is the way to go, but I couldn't figure out how to do it, because when the model was imported, it created this complex node system for the textures (for each one) and when I unwrapped the model, some were corresponding to a texture and the others to the other texture, like in this pictures:
My question is, what should I do to create a single texture file, only with the parts that are used and how to replace the existing ones with the one that I make.
Also, I'm sorry if this may seem like a stupid question for some of you, but I've just started working with textures, and it's proving to be a little more difficult than I thought...
