Texture painting on backface I'm new to Blender, I have modeled a naga and I'm painting a texture and some parts are unpaintable from the out of my model.

Them parts are "back faces", how can I enable painting on them from both sides ?

Edit : Here's the exact symptoms, I cannot draw on the part at right, the undrawable part disappear when checking the "Backface culling".



Black lines of the undrawable part have been made from the inner of the head.

It's my problem, I have disabled the "Norm" option  and now I can paint everywhere. This option is located in the left panel of 3D View in texture paint mode (show with T) > Option tab > Paint by projection > Normal

Uncheck it and  nowyou can paint on faces at 180° of the view...
