I have a test scene to show my furstraiton. a scene file from Maya 2009.
What id like to do is have the physical shader, and the fast skin shader co exist in my scene, that is all!!
left sphere - fast skin with green epidermal scatter
top spere - dielectric sphere with caustics enabled, showing that the photons are indeed working.
right sphere - physical shader that doesnt work if the fast shader is in the scene. If you replace the skin material with a lambert for instance, it will work again.
Can someone please help?
