Description:

HDRI Splitter - Control sky background and sky illumination independently. Make sure you load this blend with the UI intact to get a fast example with instructions.

Does your HDRI lighting ever look wrong, but adjusting the strength doesn't help? This is a Node group that takes two inputs: the sky background image and the sky illumination image. This node will act like a standard HDRI background setup if the same background image is attached to both inputs. One example use: split off a copy of your background image, lower the brightness, then attach to the illumination input of the node. Now you can control how much your set is lighted without changing how the sky looks (or vice-versa). New version 6-13-2015: Glossy reflections of the background that do not match the actual background look weird. Now a control called 'Glossy Blend' will allow control of how much the glossy reflections will show the 'Illumination' input. Most cases will leave this at zero. Perfect example: when the ocean and the sky meet at the horizon, they almost always look exactly the same because at a distance the water acts like a perfect mirror.

    This is exactly what I need. I'm 99.99% sure this is going to turn up in a video project and when it does I'll be sure to give you credit

    Nice! Sorry I didn't see this message till now. Glad you like it. It is a standard node in all my world setups now. I have seen several tools similar to this but they seemed hard to use or part of bigger package I wasn't interested in. Hey, if you give me credit somewhere it would be nice to see the result, maybe.

    Well crap! The new website did not copy over the number of likes so now I'm back to zero! (it was in the dozens)
