After I import a .3ds model, then select the brush tool, the paint either seems to mirror itself on the model or paints the entire y axis. To give you an idea of what is happening: If I dab my brush on the model a dot appears symmetrically on both sides of the model. If I use one small stroke the entire y axis on the model gets painted. I'm obviously doing something wrong here, and need some education or Tutorials. However I have not found much discussion of the issue I'm having. Most of what I'm seeing says Import > Paint.
I'm using Photoshop CC
Thanks in advance.
Painting uses existing UV mapping data, if present. Short of completely re-UVing it will be nigh impossible to get rid of this and end up with something usable, but feeel free to use the "reparametrize" stuff in the 3D menu.
