This is especially bad with the Tjark Hair, which is a bummer because other than the hair clipping / skull cap edge showing in renders, it's perfect! Anyone has tips to deal with this?

    Do you mean the black marks that show on the forehead? If so, you need to upscale the skullcap a little.

    what happens  if you make the skull cap invisible?  Or reducing the scale of the portion of the skull cap that's showing - like the Z axis scale.  Or check the "fit to" setting to make sure it's fit to the correct figure? Or moving the skull cap backwards slightly?

    If you are using Iray this is a well known issue that affects many hairs that use partially transparent skull caps. There have been a number of threads raised about the issue which is caused by rounding issues in the renderer. Here is a thread that tells you how to fix:

    I will check if I can make the skull cap invisible, thank you!

    Oh yes, I forgot I read somewhere about the instancing tip. Will try this first, thanks!

    Really appreciate all of your help!
