I’ll bring to the attention of the tech artists familiar with Hair. By the way, we have a new release of the stand-alone HairWorks library and viewer available, but you have to sign up for an account at ://devsupport.nvidia in order to access it. Please send me a private message to sort out the account details if you are interested. The new build should be integrated into UE4 soon…I was hoping it would have been done weeks ago, but there have been many challenges with shadows, anti-aliasing, etc.
