Rendering help wanted

[Aaron Bailey]

Hello everybody

 

having a few problems with rendering interior scene's in 3d max 6 where i have set up fake radiosity lighting solution, with ambient omni lights, diffuse omni lights, area shadow lights and direct light's to achieve the look i want and the rendering speed that is acceptable.

 

How ever the problem is that after rendering a scene i get black spots all over the reflective materials e.g. glass, polished floors, stainless steel and that sort of thing. And I cant for the life of me figure out why and what to do to fix, I can take the image into Photoshop and fix it there. for one image thats fine, but when rendering an animation with 1000 still frames plus well thats a little to tedious.

 

Please, please help

 

Cheers

Not sure what it could be, given that it's fakiosity. I'd guess it's a material. Try making your scene all one color to test it. If there are no splothes, it is a material, but if there is spotches, then it's probably a corrupt object (just a guess).

 

If it is a material, start with the most complex, like raytraced mats with layer specularity, etc. Again, just guessing.

 

With GI, I've had problems with complex relfections, particularly some stainless materials I have that have complex bump maps (I am guessing the billion little groves causes some kind of problem with the GI).

I'd do some general checkup:

1. Make sure all textured objects are UVWmapped.

2. Make sure there's no co-planar faces in your scene

Or maybe the raytrace depth is set too low....
