Hi IES,

How can I simulate specular reflections in radiance?

So far I can only get the following result:


The renders are with 'maximum' quality. I have also tried the custom settings, but so far only diffuse reflections seem possible.

Found it!

I must add 'roughness' to the material to make the directional reflections.
If it's at 0.0 then it doesn't work.
