Thank you - I will take it into consideration.

Ah - 6 years ago.
It's common knowledge things stay static over that amount of time ;-)
As for the MR-shader - are you familiar with MR?
Because Corona's, even though it only has four nodes to connect,  - looks a little similar to MR's RaySwitcher material. But you're totally right, the network of nodes IS smaller!

Sometimes you have to work with what you're given by your client - that includes bad maps with bad bracketing. So - this is why one sometimes uses sIBL, this is why one has workarounds, like i.e the sun.
A lot of times people ask things not out of ignorance, but because it's where they are in their work-process or pipeline.


However, thank you for the daylight tip - I was trying to follow recommendations I read elsewhere and met a wall after taking a wrong turn, so that totally helped :-) 
As for the glow - I think I'll just hash it out on my own, but thank you :-)

Be scared all you want - the sIBL scripts are actually a fairly fast workflow when you're on a pipeline, and most of the time, you can, oh, I don't know, tweak the scene to get rid of the superfluous components. Also - the spheres don't render, you know that, right? 
The HDR files themselves get loaded into a RaySwitcherMat which is put into the environment slot in MR, and just the *TGA background plate if it's scanline, and HDR as a skylight.
In addition - running an HDR-file through the sIBL editor actually gives you three plates for the price of one, pretty fast, so I guess our opinions will just have to differ ;-)

Moving on back to my question - one of the reasons I started exploring sIBL in Corona, bar converting from a scanline-script import, was that I am having problems linking the sun to anything, in addition to the perpetual glow of the Corona Light
Is the sun utterly untargettable - bar linking and manual tweaking, and is there a way to get rid of that superglow in the Corona Light when having an HDR mapped to it, as few other lights in Max do that in my experience,  or do you just have to use the standard Max lights and set them to CoronaShadow?

Here's how a default Maya-Env raySwitcher is set up, just so we're clear it's not rendering spheres ;-)

Hiya :)

I was wondering whether anyone could help me?

I am currently exploring Corona with a scene utilising a sIBL set, created from the freebie set from VizPeople.com.
When you run i.e the sIBL-scanline import script, it sets a skylight with an environment IBL as texture in the middle of the scene-setup it generates, with the sun targeted at the Skylight, so they move in tandem. (and yes, I have set them to use CoronaShadow)
However, as Corona recommends we use native lights as much as possible, is there a workflow to generate a similar effect using Corona Lights?
What I am getting now when I put a map - TGA or HDR onto the CoronaLight, is just a bright, bright visible light no matter how much I turn it down that just leaves a black hole when Visible Directly is unchecked.
Or is the best way to just ignore that particular workflow alltogether, and solely use the sIBL _bg.TGA-file  as environment/direct override and then slap the HDR into the Corona Settings> Environment>Use Corona slot, and then just generate a shadowcatcher material from scratch by hand?

Thanks for any feedback - curious as to whether the sIBL default setup is of any benefit in Corona at all.
