Opacity oddness

I just re-rendered an image I did a short while ago and now I have issues with transmapped parts.
I feel like put back to Octane beta times :(
Am I just being stupidly stupid or just missing anything?

I did render this a short while ago OK, though

That's really annoying. Any ideas?

Did a test with a simple cube with a transmap in box projection.
Looks strange esp on the back facing parts.....

Very strange. Could you spawn off her arm and just send me the arm, glove and transmap, then I can have a look.

I couldn't reproduce this problem - could you send me your test scene pls?

EDIT: Have you tried adjusting the ray epsilon? The glove might be self-shadowing.

OK, I think I found a clue.
Seems to be a problem with HDR Image i used.
A test scene is in the mail. :)
