Well, it's a cloak, not wings and it's from Roxana Vampire package at Daz.  It's the default texture on the cloak.  I won't post the image because, well, that would be unethical & a violation of terms of use/copyright/etc, but if you own it you should be able to view it =).

I was encountering the problem trying to render with the P4 render engine, rendering in firefly resolved the problem.
