Hello, I know that this is more of a Photoshop question, but does anyone know of a trick or even a plugin, for Photoshop CS4 that can take the edge pixels of a layer or selection, and bleed them outward like Mudbox does for each UV shell? I tried using glow from the blending options, nut glow can only do a gradient or textured border around the edges. I've also tried searching through just about every filter, but there doesn't seem to be any solutions for this. The best thing I know of is to have two layers, one that is blurred underneath, and one that is unaltered on top, but then the edge colors would blend together, and would be less accurate.

Yes the maximum and minimum filters kind of do this (which one depends on whether the texture is darker or lighter I think). They're under the Other filter menu. You'll need to do it on a clone of the texture layer as it spreads the pixels out in all directions including into the texture, then cut out the unpainted areas from the original top layer. It works better if you do it one pixel at a time rather than over several pixels at once. Give them a go they're easier to use than explain.

Xnormal does it http://www.xnormal.net/1.aspx

Install Xnormal and it will install the photoshop filters aswell, one of them is pixel dilation :)
