Title: IR - much slower with Corona Sky & Sun
Post by: Designerman77 on 2020-04-25, 22:11:24

Hey guys, I don't know if this topic has been discussed yet.

I notice a much slower IR when using the "on board" Corona light system.

HDRs result in a min. 2X faster IR performance.
Same with environment override.

Any logical reason for this?

Hi! It's hard to tell without knowing the specifics.

What exactly are you comparing? Is the scene empty? Etc...

Hey Houska, thanks for the reply.

It is a very simple scene. White walls, a kitchen, parquet. That's all.
When the IR starts, it needs way more time to build up the picture when Corona Sky & Sun are loaded - compared with HDR.

If I may, I would upload you the scene files.
Where to do that?
