Thanks, spikeyxxx! I’m saving my textures quite often with an incremented index but in the “UV Editor” it only shows the name of the “Color Texture” or the “Bump Texture” that are also displayed in “Texture Slots” panel in my “3D Viewport”. Nevertheless, Blender always shows me the last texture versions when reopening it. This is a little bit confusing. I would expect the “UV Editor” to show me the file name of my last saved texture file. Can I understand the “Texture Slots” as a container with a label which internally links to the latest saved texture file (the one with the highest index)?
