Schlick and Henyey-Greenstein shading

We just implemented the different shading methods in our KSR-Maya-Python-Exporter. Everything is fine with the Isotropic, Phong and Marschner shading models. But the eccentricity for Schlick and Henyey-Greenstein shading seems not to work properly. The images are identical to the isotropic shading. Since this is the first time we use Krakatoa, I’m a little bit insecure if my scene setup is correct to generate different shading results. I tried values from -1.0 to 1.0 for the eccentricity phase in both shading models. According to your shading site http://www.thinkboxsoftware.com/krak-shaders/ there should be a difference.

This worked when I originally tested it. Perhaps something has happened. I’ll test it out here and see what’s up.
