Thanks KickAir 8P. I am using Daz Studio 4.5 in the view port only (before any rendering). I can’t be the only one who is experiencing this. Most of the crown of the hair is like the opacity is 25% and you can see straight through to the scalp. The rest of the (flowing) hair is ok. Very frustrating. I need to be able to fix this. Can’t have a half head of hair. :(
That sounds like you haven’t tried a test render yet — if you haven’t, then do one. Is the problem happening in the render? If not, you’re just gonna have to put up with it looking weird in the viewport, because (IIRC) it’s something DAZStudio gets from OpenGL and DAZ can’t fix it.
If it’s happening in the render also then look at Szark’s post: is the hair’s “Fit To” parameter set to your figure? Is the hair intended for your figure? In this case that’s Genesis, which means that if you’re using V4 or M4 (or any previous generations’) hair it needs to be converted — even if you’re using Genesis hair, a lot of them come with fits for Mil4 figures, and it can be easy to use one of those accidentally.
If it’s none of those then I’m out of ideas, sorry. Go to the “Help” menu option, click on “About DAZ Studio”, note down the entire version number, and post it here — somebody else may be able to help. Oh, and JimmyC_2009’s right, tell us what some of the hairs are that you’ve tried and had this problem with, even if the answer’s “all of them”.
