UV unwrapping a mesh with different object using some image textures has some issues. Specifically, in this case, I have created a table and UV unwrapped the main part(the one that is active below):
Even when I tab out of edit mode and select a different part of the mesh the texture sticks around in the editor:
As you can see, a different object is selected, the UV slot is empty BUT the texture stays. If I UV unwrap it anyway, the texture is automatically applied to the mesh portions as so:
If I hit the new button:
Blender only has options for generated textures:
And if I hit the cross button, there is no user for the texture:
And therefore, I cannot unwrap.
I haven't had much experience with UV unwrapping. What is this problem? Why does this arise? Is there a way to refresh the UV editor? How can I fix this?
