See attached OCS file ... I tried lighting up my spacestation a bit with a huge light emitter ... but even when set to 10'000, the light is so oddly weak, it hardly illuminates the spacestation to levels I'd expect, when the slider of the emission power is all up...?

Using Standalone 1.29

I get this behaviour lately too, I can't use my HDRI sky environmets because they are just too dark when set to emit. Is it a normalize issue ? HDRI domes are huge, does this affect emission power ? Now I have to punch exposure up to see it.

Yes, emission is normalized, the huge and the small sphere have the same emission properties, yet the small one seems much brighter.

Did you try one of the light from the LiveDB to get a starting place.
Both the planet shader and moon are from LiveDB

Did you try to raise efficiency ? (default value is low)

I am testing this issue here and yes, perhaps the light emission is normalized with the total emitter surface. Has this behavior changed in the latest versions of Octane?

I am having the exact same problem in 3ds max 2011 with the purchased max plugin. Very frustrating. aside from using a daylight emitter in addition in my scene I am constantly fighting lighting my scenes properly. can someone please point me at a a comprehensive tutorial for setting up lights in 3ds max?
TIA
