Greetings,
I've seen recent examples of hair made with soft-alphas in UDK, which looks like a big improvement over 1-bit masks. I'm having trouble getting my own to work.
For some reason my alpha map is causing the whole head to go partially transparent. These problem areas are receiving full white. The bangs on the left do look how I'd hoped.
Any ideas on where I'm going wrong?
Thanks

    don't use the same material on your skin and hair, do a seperate one for the transparency

    Tick pretty much all the boxes under Translucency (since by default, UDK won't sort them properly, even as a separate material) and you should be set.

    Also, few things to remember:
    -Any sort of masking will revert the material to Lambert and kill any Self-Shadow's (even the one from SoftMasked, Masked or Trans).
    -You will get sorting problems it too many separate objects are made.
    -Your specular will bleed in places you never knew it could bleed.

    So I suggest doing what Neox said, it should help deal with the problems much more easily.
