HeadUvsLayout has a really handy tool to show the edge bleeding (pixel based) for each uv shell. Do you know any script to have this in Maya. Thanks in advanced. :)
There is no script that previews edge bleeding. Assign a surface shader with a color and do a quick Batch Bake on it (Its very fast with a surface shader). Set the desired resolution and Set "Fill texture seams" to the amount of pixels you want your bleeding.
