Using Render Elements with an IES Sky Light
If you use
Render Elements on page 6336 to output the lighting element on page
6356 of an IES Sky light in a scene using either radiosity or the light tracer, you
cannot separate the direct, indirect, and shadow channels of the light. All
three elements of the IES Sky lighting are output to the Indirect Light channel.
