Just out of curiosity I've been looking at Sims 3 meshes and I extracted the afHairPigtailsLowBraids LOD's and noticed the only one's present are for the bow's. Any Idea's ?

Then I extracted it with the tsr workshop it has two hairs and two bows. One high and one low polygon version, the low polygon version is used on long distance and perhaps on low performance computers.
Delphy’s hair tool is just for hair without hats or other accessories. Tsr workshop only handle the hats or accessories with a few exceptions.

Ok thanks, I have tsr workshop but I've not used it yet I'm just trying to understand all the files I should have realised, Delphy said No Hats. LOL
