@aRTBEE, I hate to disagree with you but I've tested it over and over again in both Poser Pro 2012 and Poser 10. You load an image and attach it to the IBL light (can be an jpg or HDR, doesn't matter). It will come in with the setting "use Gamma value from render" which of course is 2.20. Render a couple of times. Maybe up to 3 times. Then I go and check the IBL and the image has switched to Gamma 1.0. It doesn't say that in the dialogue box (I checked), but you can tell because the image is suddenly very bright. Do a render after the check and the render WILL be brighter than the two or 3 you just rendered.  Load a saved IBL set from Poser Pro 2010 or Poser 7, and the image will be bright like it's Gamma 1.0 but the dialogue box still says "use Gamma value from render" Click on the image, reload it. It will come back into Poser as GC 2.20. Render a couple of times. Check the image again, and it's obviously popped back to GC 1.0.

If it loaded up as GC 1.0 and it STAYED at GC 1.0, then I could adapt some IBL light sets to work in Poser 10, but it swaps back and forth. And the really hinky part of it is that I've seen it do this swapping behavior even on one of BB's synthetic node IBL shader setups.

I'm pretty sure it's a bug and it's been there since PoserPro 2012. I don't know how to report it or if they'd even fix it because I think they now asumme everyone is using IDL and not IBL anymore. But I have used IBL and IDL together and have liked the results, until this bug crept up in PoserPro 2012. Now using an IBL light is next to uselss which is a damn shame.
