The .ibl file I mentioned above is not an IBL light. It is generated by that program to give information on the .hdr such as sun strength and placement and other parameters all of which can be edited in EZDome. The sun light that is added is an infinite light (as it should be) and can sometimes even be omitted if the .hdr has a high EV as several from HdrHaven do. Snarly has really done so much for making my Poser experience so satisfying. :) Oh and when you get EZSkin 3 also pick up some addons for the cycles surface and an addon by amethystpendant to apply BB's hair settings for Superfly - don't be afraid to try it, render times are not that long once you know what you're doing and not rendering really demanding effects.
