Point Light Map Seams

achillesian

In my efforts to figure out how to do sweet point light maps like in that dota texture guide I followed some instructions from this thread: http://www.polycount.com/forum/showthread.php?t=101000&page=2

(post 29 specifically) but I'm getting bad seams (I think it might be a texture padding issue) and I can't figure out how to save out the texture from the material editor.

Post your uvs and normal map.

yeah, there was absolutely no padding on this bake, that seems to be the problem



how do I add edge padding for this type of bake? What I'm doing is detailed in this post: http://www.polycount.com/forum/showpost.php?p=1613930&postcount=29

There is padding, if there wasn't there would be white inbetween the uv's, the stretched out normal colors are the padding, it could be an issue with how well the low poly and high poly match up, or an issue with the cage.

i'm not using a high poly in the light map bake, simply applying the normal map, that looks good, no seams when applied, and then baking the material and light information as seen in viewport into the texture

Ohhh okay, I was confused for a moment, try some of the solutions mentioned in this thread. http://www.polycount.com/forum/showthread.php?t=99349

xnormal has a photoshop filter that does the padding for you, it's called dilation there
