I'm getting these bald spots on the back of my separate scalp mesh. The hair is not combed behind the scalp, it's just not there at all. Weight painting is totally red for both density and length, and I've tried disabling modifiers like frizz and noise, and every other one. Does my model just have bad genes?
UPDATE: The shader was the culprit! The missing hair was simply transparent, but I've switched the short hair to a simple node, and it's all a lot smoother. The complex setup is still on the longer hair.
It’s hard to say for sure, I’m not very practiced on hair in Blender. But it looks quite similar to issues I’ve seen with baking normal maps where the low res mesh clips through the high res one, causing little diamond spots like these bald spots. Could it be that the target mesh is on the wrong side and therefore not finding the target location to plant a hair follicle in?
Again, I don’t use Blender hair in my line of work so I may be way off.
so the scalp mesh is just a duplication of the original head mesh, and i have it shrinkwrapped to the head. The hair is only growing out of the scalp, which is the target, and even if I isolate it, the hair is just not there. and you can see in the first image where the guide curves are, which Blender interpolates, and even if those were missing, it shouldn't do this. i hope i answered you!
I assume removing the shrinkwrap doesn’t fix anything?
Anyway, I doubt I have the expertise to solve this one. Good luck!
Nope, and that doesn't effect how the hair spawns, anyway. thanks, appreciate it regardless!
