Frosted glass

[3dloft]

Is there a way of importing frosted or opaque glass? I've tried several materials including the frosted glass in V-ray 5.0 asset browser. If not, any work-a rounds?
Thanks, Dave

Hi Dave,

Currently refraction glossiness is not supported in Chaos Vantage but it's on our TO DO list.

As a sort of a workaround you could try the following:

• Create a duplicate of the glass you want to be frosted;
• Modify the geometry so that you assign a different ID to the back face of the glass geometry (e.g. ID 2 to the back face and ID 1 to all other faces)
• Create a MtlMulti and assign the original frosted glass in slot 1 and the duplicate to slot 2 for ID 2 and assign the Multi material to the glass geometry;
• Add a noise bitmap texture in the bump slot of the duplicate mtl.
• Set the tiling to something very high e.g. 50-100;
• Now you can control the glossiness by adjusting the bump strength.

Here is a link to a demo video showing the workaround:
