Suggestion of "merging emitters" is rather useful with the physical sky because, the sun itself is a very powerful emitter. You should not generalize such a rule for every scene setup.

well i can confirm it is also valid for emitters + IBL

i hit the exact same problem.. that is why i posted this :

after fixing it, i got perfectly detailed hard shadows from the HDRs, and the fireflies went away...

Yes. Just like sun or a relatively powerful emitter, a certain IBL may also do the same. Try to focus on the main reason and see it's the huge energy difference between several light sources to be rendered. It doesn't matter it's a sun or a pixel on a HDR.

Did anyone explain why sometimes the preview is purple?

Which one would fragment the drive more, multiply the seek/read/write access times and finally slow your harddisk (and so the computer) down?

1000 files made of 1 KB or 1 file made of 1000 KB?

Conclusions:
* It's true in v2, you don't need to merge them for ML.
* You may not like to merge them if you have a few emitters.
* You definitely need to merge them all (or at least as groups) if you have tens/hundreds of them especially together with sun.
* You should find new total lumens for merged emitters or change your emission strategy in terms of units. (e.g. lux or luminance)
* Pink preview is a current preview-engine limitation with Multilight. It has no negative effect on your render in any way.

This is just an optimization handicap but all these methods will give you the same look in final render. The word optimization roughly stands for the importance of samples taken per emitter. Otherwise, Maxwell has no sort of tricks or shortcuts as we clearly mention with patience and passion, over and over. It's your benefit to turn optimizations into advantages. Thanks for understanding...

Ok thanks...

You're welcome.

I hope this issue can be resolved (optimized). Not having to join emitters in 2.0 was an improvement that is basically being negated for most people doing interiors with sunlight and a moderate number of emitters. Having to wait for a high SL to see the sunlight is not a very elegant work flow.
