Hey everyone, I'm following Kai's hair and fur Masterclass in 16, I'm currently on H18 now. So after following the basic guide groom>guide deform>guide simulate> hair gen, the hair gen with following the guide sim well and overall the sim looks good. But my hairs are flickering like crazy.

If I try reducing the density of the hair gen it fixes it, but I need to have dense, realistic hair. I tried more substeps, decreasing hair gen radius and falloff, as well as turning off all collisions inside the guide simulate. Still the same. Any ideas.

I'll try attaching a render to show problem.

Thanks!

Normally flickering of that kind is caused by scattering changing per frame. What does your setup look like?

So I found the problem! In my hair generation node, my influence radius was way to big (3) I had to lower it to about .25. This was causing the generated hair to be controlled by to many different guides, so it was confused. I also increased density from 350 to 700 and increased my influence decay to about 3.

There is still some flickering, but I know this is from the render. I'll have to change the diffuse or SSS.
