What happened to the hair

[Cali Souther]

Upgraded from classic SL head to the free one from Genus.

Now hair pops out like it's not attached.   Any ideas?

I've tried adjusting the head shape,  but nothing seems to work.

Any advice is greatly appreciated.

   Hm, that looks like an alpha conflict somewhere. Either your system hair, or the hair glitching with itself (yeah, they do that sometimes). Check your system hair, and if that's all in order I'd just re-attach it to see if that fixes it.

Hmmm..... it was the brow shape ....     how very strange !!!    Thank you SO much.

That happens if the system hair is textured with a transparent texture, but the sliders aren't pulled all the way in

Our SL bodies are weird lol

Complicated, for sure!      Thank you!

Sometimes you can fix this with a head alpha. Some of the major hair stores (Truth, Magika for example) will include one in their hairs, or you can probably find one on MP or just alpha it from your head HUD. It seems counterintuitive that you can alpha the back of your head and it will fix the front of your hair, but somehow it works.

   The head itself is not a factor, the only reason I could think of that it would fix the issue is that the rebake and avatar update nudges the alphas into compliance (much like right-clicking an alpha blended mesh can temporarily 'fix' it on your end).

   The issue is with the system hair and the alpha hair crossing through each other; Second Life can only ('really') render one alpha blended mesh at any given angle, if there are two surfaces with alpha blending in front of each other, the surface in the back will just be turned 100% transparent. This is why long alpha hairs don't work with transparency in clothing (such as sheer tops and dresses) and why multiple applier layers of mesh bodies usually didn't work (i.e. having a tattoo on your tattoo layer and then wearing an underwear layer to pop on some stockings would completely turn your tattoo invisible). The only 'fix' is to turn either of the faces to alpha mask mode (wherein any given pixel is either transparent OR opaque, unlike alpha blending which can have transparency of any given pixel by a percentage) - but alpha masked textures don't have that smooth transition that alpha blended textures do (a bit like having its built-in anti-aliasing).

   System hairs are a mandatory attachment (just like skin, eyes, and an avatar shape); you always must have one (and almost certainly get bake fails if you somehow manage not to, or somehow manage to wear two - i.e. turning into a red cloud/white orb), and because of how it's mostly used for its extra sliders for the brow's shape it's commonly referred to as a 'brow shaper' instead (some people also call it a 'hair base', but that's also something entirely different). And, because the system hair alpha was a non-issue (or at least less of one) back when people used fully opaque sculpties and mesh hairs, a lot of older brow shapers included with body shapes and the like never had their sliders pulled down - just like foot shapers made before BOM often had their textures left at the default settings as they were only used to adjust your avatar's hover height, and now give us weird white socks if we use them with a BOM enabled body.
