Hi everybody.
I just noticed a weird behavior and wanted to ask the guys of Nextlimit if this is intended.
I got an interior rendering with a huge glass front and I am using the physical sky + sun to lighten the scene. For some reasons (mainly quality) I don't want to use AGS. But it works really fine with glass and clears up pretty fast. Some windows are open and the light falling through is a bit brighter, which seems realistic and looks pretty good. So far - everything is perfect.
Now: When I want to use any other light source in the room (say an emitter with IES), the direct sunlight through the windows which are closed, is not visible anymore. Is this intended to be?
I'm using the workaround now, to render the scene once with only sunlight and once only with the emitters and combine both in Photoshop. This should work fine. I'm just a bit confused, that it does not work with both combined ... Is this a bug?
Cheers, kami

I think this is about the balance of the strength of each emitter in the scene. It will be fastest when your emitters have similar values but in cases where you mix a very strong and very weak emitter you will see more noise. What you can try is raising a lot the strength of the emitter you added and lowering it's strength to the intended one using ML. See this post:

But then, exactly the opposite should happen...
The sun must be considered very much stronger compared to 5 lights with 100W each?

Good point. I'd also be curious to hear the answer to that question... Having similar problems at the moment and I'm not happy
with more 'work arounds' such as insane sampling levels of 35 or using ML all the time. Hope all this will be addressed and fixed
soon. Thinking of rolling back to previous releases once again. Not good.

The answer is in the bugs section, and imho it should be sticky.

So adding an emitter to a phys sun scene causes light to no penetrate glass? That's a pretty bad bug.

Agreed.

thanks for the confirmation.
