Drawing in a UV MAP

Miscellaneous Forums/Content Creation Tools/Drawing in a UV MAP

Does anyone know of good software for drawing within an Exported UV MAP... Say I export a Bitmap from an unwraping tool... The bitmap has a white outline of all the UV space. What would be a good tool, or proceedure to draw, and get rid of the white lines, besides magnifying and erasing pixel at a time.

Eric
