Quote - Boom.. when you make your Vue sky ibl's.. what do you do?  just make your atmosphere and set it to panorama render with the 180 degree overhead setting?

Pretty much. Load atmosphere, make a few changes with the Atmos Editor, set the render settings (right click on the camera for the short cut), though I usually render at 16:9 and 2133x1200 at 240dpi. Also for an IBL type, you'll want to use the Panoramic setting (think its the top one) and click the 360* value. 

I've found that the EXR makes for a great IBL as opposed to the HDR (as it translates onto the Studio spheres and looks right/unstretched as a background image), but I save both and a PNG in the event I need it for an icon somewhere.
