So I'm working on a character where I have hair assigned to curves and the character's skin has a SSS shader on it, and I'm rendering with final gather. Seems like no matter the settings I use, the hair pass comes in pure white. Anybody have any ideas why this is?

Ok, I figured out the cause of my problem, but not in a way that makes it go away.

It's the light settings. I have a setting of 900-500 on my various lights as far as intensity, but that's because I have them set to linear decay so they fade off. It works for all the models in the scene, but it looks like the shave hair doesn't handle the linear decay part of the light so the hair is just supper lit. Is there a way to get shave to handle that?

If I turn the lights back down it seems to render fine. Is there a way to make shave hair into geometry?

And never mind, yes I can, then it works, so solution found.

How do you change shave into geometry.
