I did some tests with Internal, Cycles, LuxRender
With this engines, i can set material that have specular reflectance.
Here is a example image from cycles.
with Yafaray ShinyDiffuse i get this image:
Notice, that it have no specular highlights
And the mirror-effect is sometimes too high
So how can i set specular-material with control for IOR & Glossy-Roughness?
