Glass Rendering

Re: Glass Rendering

Hi Dave
The file is a Rhino file.

Lukeorford, there are different types of noise. Noise produced by the anti-aliasing, lights, etc. In this case the noise looks like big stain, so are Irradiance Map splotshiness. You can increase the HSph Subdivs. Other thing that can produce that king of stain is the HDRI. Try to use a blurry version on the GI Color.
Other point is that V-Ray throw less sampler in a dark image, so try to improve the illumination.

Sir Fernando,
1. Noise produced by the anti aliasing, lights etc - is this dependent on your scene setting? are there any rule of thumb when tweaking the AA parameters? I usually go with adaptive dmc.

2. the noise looks like a big stain. - when increasing the hsph subdivs, does this also increase render time?
again, a rule of thumb for these parameters? I watch your video regarding the irradiance map settings about the HSph subdivs and samples. But I'm still confused on the min and max rate in relation to the output or resolution of my render.. I usually go with 600x480 at IRmap -3,-1 and then at 800x600 IRmap is -3,-2 etc

thanks
