I am having a similar issue. The figure looks like a mirror or reflection of the IBL (1st image).
I have done test renders with the image showing properly. This is a custom DAZ Gen8 figure I am testing. I was able to to get the figure, hair and clothes to CC3 with no problem m(2nd image).
I'm sure it is operator error somewhere, but I check the Iray settings to compare with my first test render and they are the same as far as I can tell.
Thoughts?
Thanks in advance!
