I would appreciate guidance in this matter if anyone has any to offer. I am very new to 3D Painting in Photoshop but I am nominally knowledgeable of Photoshop in general for 2D work.

I exported Genesis to an .obj file and painted on it in Photoshop 5.5.

When I paint on his face, other marks show up on his torso and thigh and eyes, even.

It is like all of the diffuse maps are "stacked upon one another" (though not in layers.)

If anyone has experienced this or knows a good solution or tutorial about this, please share that info here.
