Well, yes and no. It works on the Poser 4 part on any CR2. It does not alter the Poser 5 material specifications. (Since it was originally designed for Vue users, and Vue doesn't import Poser 5 yet, we didn't put support in for changing the Poser 5 materials yet.) Also, it does not change the transparency, at this time. (It wouldn't be hard to add that support, though.) lynn
