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.

Hi epilectrolytics, thanks for the tests and feedback!
We are testing the bake tools and we are progressing. One question: once we have the baked scene how do we can render it fast on luxcore? i mean how do we disable GI to save time and raytrace only transaprencies and reflections? Or is this ...

Hi to all. It seems however that in complex light situations flicker free animations are still tricky to achieve. The animation i published previously, by mistake, had a very low clamping value which made it so stable. With the correct clamping value, showing up lighting correctly, the flickering is ...

Bartek has been able to fix the luxcore code!

We share the code on github now.
