Whats the best way to deal with ligh map seams?

StraightDraw84

Say you have a cylinder in 3ds max that you export to udk, now the obviously the cylinder will have a seam on one of it's divisions (uv layout) which will translate into a seam in udk when using that as a light map.

Are there any tricks to get rid of that seam instead of just trying to hide it with another object?

Thanks!

so long as its lightmap unwrapped properly it shouldnt have a problem.

Hey thanks for your reply, but the link doesn't explain how to get rid of that seam

I think this should answer your question. It is at the bottom of the page he linked you.

The guidelines on this page will help you avoid seams from diffuse static lighting, but there will still be seams in lightmap specular. The only way to avoid seams due to lightmap specular is to use a light which calculates lighting dynamically (Movable, Toggleable or Dominant). See DominantLights for more info on dominant lights. Even when using a DominantLight, the indirect lighting is in the lightmap, so lightmap specular from the indirect lighting will cause seams, but they should be much less noticeable.
