Wasn't aware of those effects shaders - I'll have to take a look.

I've just been playing with the Env Sphere again briefly, returning to outdoor scenes. I keep running into problems with the Equirectangular Maps not quite being Hi Res enough for my final output. 

Other issues I have managed to solve when using it with IDL include one where the background (i.e. the EnvSphere image) was rendering differently each time I made tweaks to the sphere's HSV node. I'm now using a dummy Env Sphere scaled 1% smaller than the one actually interacting with IDL and made non shadow casting & invisible to RT  - the dummy Sphere renders a consistent background even if I make changes to the one seen by IDL.
Also I found when using the ground plane as a shadow catcher with the Env Sphere that a lot of light seemed to never be making it to my figure. It turns out that even though the ground plane was just a shadow catcher it was still acting as a barrier to the light cast by the sphere from below and by making it non shadow casting & invisible to RT suddenly everything brightened up again.
