Hi Farbige Welt, first i want to thank you for all the tests you did, very interesting.
What i need to do now is to fully isolate the trouble making situations which takes a lot of time. My problem is not only noise related but more about the fact that, under certain circumstances, the same scene ...

Thanks Code HD!

Hi to all,
i want to share with you my latest 4k animation show reel, entirely done with FELIX render running Luxcore as rendering engine.

The kind of light also is important, if you want comparable brightness define lights as physics not as artistics. I prefer to define brightness of lamps in lumen.

EDIT (facts you probably know well)
Another big influence on the brightness of light is its area.
A further influence is the maximal ...

I don't know how the Metropolis algorithm chooses its generated Random numbers. Actually if it works with a seed number it should always produce the same series of generated random numbers. A developer should be able to check this.

Did you already check if your scene contains lamps with many ...

It seems the fault of the brightness variations is to address to the metropolis sampler. Metropolis delivers frames with much less fireflies but with larger lighting discrepancies between frame and frame. If i use the random sampler this problem vanishes but the image starts to be full of fireflies ...

the following frames have only a few mm camera translation but still the brightness variance is enourmous. BIDIR renderer

Hi Farbige welt, yes we use high ray depth values in order get even the most complex scenes right. Our users are not aware of render related issues so we want to give them a zero settings solution. For static rederings Bidir as we have it, works well.

LOG_POWER changes completely the lighting ...

Hi, at the end we opted for a different solution to produce animations. Our requirement is to a achieve zero-set-up solution.
Precaluclated GI caching and so on need to much scene dependant tweaking while metropolis is too slow, GI baking is impossible on complex scenes.
So the we opted for an ...

Thanks epilectrolytics, let's see.
