Hm, maybe it is related to this issue? https://github.com/LuxCoreRender/LuxCore/issues/70#issuecomment-374547898 Which renderengine and halt conditions are you using? Are you using tiled path? You could try to reproduce the issue with a very simple scene (cube on a plane) and see if it also happens ...

That has nothing to do with your problem.
Look into the camera settings, disable the automatic tonemapping.
If you need it I can post a screenshot.
The wiki section on this topic is not yet written unfortunately.

Maybe you are using an automatic tonemapper?
See "when I change the brightness of my lamp, nothing happens"
The tonemapper settings are in the camera tab, imagepipeline panel.

There is also emission Emission is already setup in the preset. You can get it with the following steps: Create a cube Press spacebar -> search "quick smoke", enter select the smaller cube that is emitting the smoke, go to the physics settings, change emitter type from "smoke" t...

Ok, then I leave that to you.
It's not time-critical.
The exact spot in the code is here: https://github.com/LuxCoreRender/BlendL ... ts.py#L176

Me too.
I will have to rework the "fire and smoke" preset in BlendLuxCore, currently it does not include scattering (only absorption) because that was so slow, now I can add it.

It is already available (TILEPATH engine).
In BlendLuxCore, it is available in the render settings: Just enable the "Tiled" checkbox.

Some engines use different integrators for primary/secondary bounces. E.g. V-Ray: https://docs.chaosgroup.com/display/VRAY3MAX/Global+Illumination+Rollout#GlobalIlluminationRollout-DefaultParameters edit: their nomenclature is a bit weird, I think with "primary bounces" they mean the first...

Use one small, dominant light source in the scene (e.g. a small meshlight or a sun light).

You can render caustics with an unidirectional pathtracer, but it is going to take much longer than bidir to get noise-free in most scenes.

Can you post a test .vdb exported by Blender for testing ? Here is the same simulation baked with 3 different compression methods. I also added one version with half float format (blosc compression) - the others support this, too. Download button in the upper right corner. https://drive.google.com/...
