Glitchy rendering issues with hair scalps/caps

Diaspora

So, I'm getting a lot of weird glitches lately with the scalps/hair meshes of hair assets.

For example, in the attached image I have Olympia 6 with flirty hair and you can see those weird circles on her forehead but this is also an issue with other hair assets.

Setting instancing optimization to speed seems to lessen the issue but not eliminate it.

How would go about fixing it?

It is caused by overlapping geometry, usually due to lack of precision.

Either try to change instance optimization in render settings to either memery or speed. Or scale the haircap a tiny bit - some haircaps has a morph for that.

Yep, as @felis said. Most hairs have pre-made morphs that will work with most head shapes. But cap won't always fit perfectly and geometry of hair cap and head will overlap. Creating those glitches.

Resizing the hair cap (bigger) fixes that all the time. I usually always scale up (using pre-made morphs coming usually with caps) hair cap 10 to 15%. And I don't ever face that issue anymore.
