I'm having some issues with fresnel reflections in the material editor. They suddenly stopped working correctly.
In the top set of images the first doesn't display any fresnel properties. The second, after lowering the reflection amount, shows a hard circle where the falloff should be.
The change in the next set was the cutoff from .01 to .001. (I copied and lightened the preview box to make them easier to see.) I had read on the forum that changing the cutoff helped some people with similar problems several years ago, so I tried it. It appears to get better, but the lightened .001 image still seems a little weird.
The last set of images have the diffuse map off and compare fresnel reflection with a fresnel falloff map.
Any ideas about what's going on here?
I'm using vray sp2, and probably can't upgrade for a few weeks (render farm issues). Thanks for any help.
