Grainy refections and refractions with direct computation...

[mzmeskal]

Guys phease help me with this.... I dont like to use interpolation method for refl./refract., I set the samples for direct computation to 50 and I still get graininess, especially in refraction....how shoul I solve it? cos I dont really want to go back to interpolation since it produces some really weird results on the edges...

Thanks for suggestions....

What version? there was a bug a couple of releases ago.

That would be the j version, but I am satisfied with it otherwise....stable and quick.....

....so U think it might be a bug????

I dont know I think that 50 samples is far enough to take care of graininess with direct computation.....

How should I set up the interpolation to get clear result on the small edges....

The last I use was -4,-1.......with 30 subdivs....and 30 samples....
