I have been doing some renders with V6 using the default Belle materials. I have noticed some issues with the eyes. For example, look at the eyes in the render below of V6 and G2 Female that I posted in the V6/G2 render thread. V6 is in the white and black dress. G2 is in the red dress. The iris of V6 eyes looks washed out. It is hard to tell what color her eyes are.
I have been looking at the surface settings trying to figure out what is causing this. The diffusion textures for the iris are not washed out like this. I have been fiddling with the eye surface settings and I think I have found 2 things that are causing this.
1) The new G2/V6 surfaces have an EyeReflection surface, in addition to the Cornea, Iris, Pupil, Sclera. The G2 skin surfaces have nothing set in this, but the V6 surface has the opacity at 15% with a texture and reflection at 10% with a texture in the reflection color. The texture used in both is a black and white street scene with buildings, cars and people. I suppose this is suppose to be reflected in her eyes somehow. The V6 Belle skin also comes with 3 eye reflection presets, but these presets do not change the EyeFeflection surface at all. These presets seen to change the opacity in the Cornea surface with a texture. There also is no preset I can find to remove these reflection presets once you apply them. The settings in the EyeReflection surface seem weird.
2) I think the SSS setting in the Iris are too strong and washing out the Iris. In general the default SSS settings for V6 is way too high in my opinion. I have been using the SSS 25 preset. I’m not sure that preset lowers the SSS in the eyes though.
The second image shows close up renders the the default V6 eyes with the SSS 25 preset, then with the opacity and reflection turned off in the EyeReflection surface, then with both the EyeReflection and Iris SSS turned off. The last render seems to get the eyes back to something normal looking.
Is this a problem with the material or is this the way it was intended to be?
