I’m curious if this is a setting I have on my lights or if this is a known issue with the experimental hair in UE 4.24. This issue happens when a light is facing the camera behind my geometry (my rim light) and the ‘cast shadow’ is checked. When I zoom in or out the shadows turn on and off and cause my skin shader to glow. If I uncheck cast shadow the issue goes away but I get light bleeding from those lights. Not a huge deal just curious if anyone has run into this type of issue with the hair. If I delete the hair from my scene the issue goes away completely.
