[Radiance-general] Preview error - unknown object type "ashik2"

[Georg Mischler]

Is there any documentation on how to actually use this material?
So far it is only mentioned in a release note and on some presentation
slides, but not explained at all.
What are eg. useful input values for "specular power"?

Cheers
