Artifacts in maya baked lightmap
polycounter lvl 18
Hi, I'm baking a light map using mental ray in maya. But it has some ugley artifacts, it looks like this.
You can se the shadow of a tree suffering from these squear tears in the lightmap. And they apear all over the lightmap.
These are the settings I use in mental ray baking options:
Color mode: Only light
Normal direction: Surface front
Bits per channel: 32 bits
Number of samples: 8
Final gather quality: 10
Final gather reflect: 0
Fill texture seams: 5
I had the same problem with the Occlusion pass, but it could be solved by using a highter number of occlusion rays, this solution of course can not be applied to the Lights only pass.
Any ideas to adress this problem would be highly appreciated.
Thanks

I did try different texture seams but it didn't have any effect on the artifacts. But then I tried turning if final gather and found the artifacts are based in the indirect lighting rendered from the final gather and no setting seemed to change it. So now I'm trying to think of other more accurate render methods to create same luscious light map but with out the artifacts.
But really thanks for trying to help
