Let's say I have a cube with two materials assigned to it: cat and dog. The cat material is assigned to one face, and it's a simple image texture node with a picture of a cat. The dog material is assigned to another face, and same node setup.
Now I understand that a model can be assigned multiple materials, but each face can only be assigned one material, and so my question is:
Is is possible, in the texture paint mode specifically, to create a painted line that would start from the dog face and end in the cat face? If so how?
Now it seems to me that it's not possible unless you make two textures (splitting your painting in two in this case), one for the dog, and one for the cat, but I'm a beginner so I still hope it's possible somehow in a simpler manner...
