Strange normal map errors

jackanimated

Hi all,

I've been getting on quite well with normal mapping to a point. I still get strange missed rays and other errors which I cannot seem to fix or figure out why they are happening.

Here is my latest map:


As you see there are some missed rays on a small number of areas. Its weird because these areas are coompletely flat on the model and totally within the cage. Any ideas?

There other issue is the white areas, I have no idea what these are, in particular the large rectangle on the right side. In geometry this is the bottom of a mattress and is turbosmoothed, so why am I getting what look like geometrically shapped highlights?


Any help to figure out these last teething problems would be greatly appreciated.

Thanks

Are you rendering in 3ds max with mental ray? If so, trying setting the visibility of the projecting model to 0.0 (or try rendering with scanline)

Yeah, the low poly is already transparent so it isn't that. I could try with scanline then.

Totally worked. Thanks!
