Hello!

Thats definitly Z fighting… Overlapping exist on the closer mesh too…
Is this simple rigged skeletal mesh? so no hair / fur simulation or something attached to hair?

If not that must be resolved in modelling program, try to raise hair a littlebit to avoid Z fighting

Thanks a lot for reply.I’ve already solve this problem by using the command line r.SetNearClipPlane.And put it here to help people who may have the same problem.
