Hair problem

carondimonio5

Hello there are some hair that give me this sgtrange behavior in renders. Is there an option to tweak in order to seem them nicer?

Seems like a low quality render, but just with hairs... rest is perfect

This is a known issue with the current version of Iray.

Not too sure if you're able to, but I've found the adjusting lighting and having backgrounds solve the issue for me.

@carondimonio5 You could try:

With the Hair Selected in the Scene Tab, go to the Surfaces Tab and select all the Hair's Surfaces except the Scalp, then go down the list of Surface Parameters and look for SSS Amount.

If that's present, try setting it to Zero. It seems to be part/one of the "Issues with the current version of Iray" and doing this has at least temporarily solved this same issue for several others who have posted very similar looking renders.
