VRay SU Glass

[vinuvergis]

Hi ,

I am very new to vray and have been messing around for a while with materials and basic interior renderings.

I think I might have got a decent glass door, but I have a mysterious blue below it.

No fog is turned on.

Any idea what this might be. Also any tips on how i can smoothen the shadow noise. It seems quite pixelated. Any relation to the size of the rendering cause this is a small size render.

Thanks guys

Hi. Mysterious blue color could be reflection from some blue material in the room. Or it could be reflection of the sky if you have some big opening.

About the noise, you should check youre image sampler and make sure that it is on 'adaptive QMC', and try something like this...

min subdivs 2, max subdivs 4.

Make sure that you got the 'use QMC sampler' turned on.

In rQMC sampler you could try noise threshold at about 0.001-0.005 (the smaller the better...

You could play with other parameters in rQMC in order to get this image perfectly smooth.

Hi. Marko04 is right. The QMC sampler will give you excellent results for a value of 0.001 but you'll have to wait a lot of time to see it. The default (0.85 and 0.01) give decent results in most cases. You want to play with these values very carefully. On the home page of this website, look for THE VISUALIZATION INSIDER. You'll find a lot of tutorials and explanations on vray. Good luck.
