Thank you. It seems the following two were the finish related changes
mentioned earlier in the discussion ... did I miss some others?
* A new finish parameter use_alpha has been added to suppress highlights
and reflections depending on pigment transparency
* Fresnel angle-dependent attenuation can now also be applied to
highlights and the diffuse component for more physical realism
The use_alpha looks useful indeed. So far I gave highly transparent
glass very little specular highlights to avoid the problem.
I'm not sure how to make good use of the second point though?
