* Vanilla Orc hairs for women are modeled ''terribly.'' You'd expect the non-hairline NIF to contain the bulk of the hair and the hairline NIF to just have the parts that need to blend; in practice, ''both'' NIFs contain the bulk of the hair, and the hairline NIFs' bulk actually covers the non-hairline meshes. This wouldn't be a problem except that while most of the hairline meshes are therefore opaque, alpha blending is enabled for the whole meshes, and that prevents EffectShaders from affecting them. I'm working on a fix to go in my "tweaks" mod, wherein I edit the hairline NIFs and split the meshes. | * Vanilla Orc hairs for women are modeled ''terribly.''

** Tutorials claim that changing the "flags" on the NiAlphaProperty will fix EffectShaders. This is misleading. The "flags" aren't a bitmask; they're actually the entire set of alpha settings. Moreover, it's really only ''one'' flag inside of that data that has an effect, and it's the flag to force one-bit alpha with a threshold (as opposed to a smooth blend, which is what the textures are designed for). So no. That's not a fix. | |||
