Glass help?

Ok, so here’s my first post. I am trying to get the hang of this VRay stuff, and so far I’m a fan. One of my problems, despite the great help from some tutorials I’ve read, is glass. Attached is a render that I have done with some simple ring models. The colored stones are my focus here, and I just can’t seem to get them looking right. Most of the tutorials I found were geared for Max, and there seem to be quite a few differences in how the controls work. I guess what I’m looking for is some help on getting the reflection/refraction settings just right. Any help is appreciated and thank you in advance.

Hi,

here VfR tutorials:

Some hints for your scene:

- set at the global switch at higher max depth for reflections. test some settings. :wink:
- disable “double side” at the glass material options
- be careful with the fog color (did you have used it?)
- be sure, that the glass and the ring dosn’t intersect.

Thanks for the quick reply. Yeah, I figured I would get myself in trouble with the fog. I’ll try what you have suggested and see what I get. Thank you again for the help.

Actually double side option should be checked, and reflect on backside should be checked for realistic glass.

I have seen now, it work other as in the beta time. But it is good now. :slight_smile:

There were many different stages in how the BRDFs were calculated during our long beta. So now it should be ok with the double-sided. I believe it is related to us always using volume fog now.

Joe, is it possible to place the reflection layer befor the emitter layer. Often, emitters has a glossy surface like monitor screens.

Not in the current version of V-Ray for Rhino. We can look into making the layer type order less restrictive.
