I have built 86 AFAIK and sometimes I get some errors, but that's got more to do with the firefly setup.

Transmapped hair is a very difficult thing to setup a shader for. a lot depends on the original textures that were used, but also on the geometry of the hair figure or object. I included a cycle hair shader in my plugin and some hairs renders great ( ye olde kozaburo hair works great) but some modern hairs look like s**t.

I've made a good shader for dynamic hair so I use a lot of dynamic hair these days, the rendertime has improved hugely with older version of poser.
