Hi.
Well, in games with characters creation you see that you can put different tattoos and images over the character you are creating, so, I don't think these tattoos are in the uw map of the character right? (I'm new), so how tyhey add images so easily over a character?
Each character has a material with layers of textures attached to it, these textures are mapped onto the object using UV.
Tattoos can be added by adding a transparent texture over the other layers and drawing onto that layer image, each model will have its own material but share there textures.
If you are only using a single layer texture you can directly draw onto that texture, this isn't advised as you would have to create a new texture for each model or all the models sharing this texture would have the same tattoos.
Thanks, I would look into it.
