To get an idea of what it is being used for is a texture burned car body for a low-polygon model. I used Max 5 to export the texture, with no anti-aliasing against the background, so I have a nice sharp edge against the black background of my texture, and an alpha channel to select the geometry outline from also.
Now, since Max renders these "burnt" textures with no overlap at the edges, it leaves artifacts on the textured model, where the edges may have aliasing lines along them, or bleed the black background onto the actual model.
Obviously that is unsightly, and due to the random noise and delicate shading of a GI texture, it is very hard to remove the sharp borders effectively, without spending hours going around all the edges, cloning several pixels out of the edge colour.
Now, a plugin that simply detect the nearest colour, and then borders with that in mind would be great! It'd save me hours of delicate colour matching work, and make the textured model neater too!
I've already tried cloning and blurring the layer lots, and then removing the interior and exterior beyond 3 pixels, so I just get a band, but it is far from perfect, and tends to leave nasty artifacts which again, show up badly on the textured model.
Anyway, I'd appreciate any help, or ideas on this. Any plugins that might achieve an effect, even a half way one would do...
Odd why Max 5 developers never thought of this, since one of the main features of this texture burning is for low-poly modellers and game content creation...
Thanks in advance!
