Is there a way to increase the padding after rendering a texture?

Joltya

So I'm rendering some maps right now, and due to the somewhat unconventional pipeline I've set up for myself, I can't have the padding too high or else the textures will bleed over into eachother. However, the padding I have right now is too low, and there are some very visable issues near some of the seems. I'm sure there has to be a way that I can stretch the pixels from the edge to fix the problem, but I'm not sure how. Does anyone know how to fix this issue?

Photoshop has several methods for edge padding:

Solidify.
Solidify is a free filter that pads out the edge pixels and blurs them together.
Filter > Other > Maximum.
Before running the filter, fill the empty areas with black, and make a non-anti-aliased selection of the empty areas. Beware that when the padding overlaps itself, it does so additively, over-brightening the pad colors.
Xnormal has a Dilation filter that works well.
Before running the filter, make sure the UV shells are together on a single RGB layer, and the gutters are transparent (deleted).
Eric Chadwick has an Action called UV padding from Alpha that adds an 8-pixel edge pad.
The Action is slow, but it greatly reduces pixel-streaking and is non-destructive. Before running the filter, make sure you have a non-anti-aliased alpha channel, with white shells and black gutters.

Awesome thank you so much!

Xnormal comes with a Photoshop plugin called dialate that is perfect for this
