Hi all
I want to make a translucent glass. I don,t know this material contains of which categories of radiance materials? How can I create that? please someone help me.

See trans material component. There’s is a link to a presentation from radiance workshop about setting up translucent materials in Radiance.

Thanks alot. but I just have 2 properties of this frosted glass, which are visible light transmittance and reflectance ,and I don,t know how do I set direct and diffuse transmission and reflectance.
