Hair system issue - 4.24

Hi guys, I’m new to Unreal and I have some trouble with the hair system (4.24). I’ve imported the hair that I’ve done in Maya with IGS, Xgen and there are some problems with planar reflection. The hair has a lot of noise, and I can’t figure it out. I’ve turned off raytracing because with raytrace reflection on the hair, it results invisible.

I’ll post there some screenshot, so you can see what happen.
