I found strange behaviour while using smoke in blender and rendering it with Lux. Here u can see example scene: smoke domain intersect marble dog figure and enlight dog volume. Figure is smoke collision effector and doesn't really intersect smoke. If change priority value of volumes - it can only cut a part of dog but nothing else.
To see difference just disable smoke domain rendering in outliner

Blender 2.9, Lux 2.5 beta1

Scene for testing: https://drive.google.com/file/d/1e3GifT ... NPTnX0Y_U/

Interesting scene, the spotlight seems to be the problem, it illuminates the smoke and visually cuts the dog in half.

Okay, seems no one knows where problem is. May be anyone knows how to render smoke in different pass with shading from original objects and combine it?
Just make all other objects holdout?

Spotlight appears the problem, not cause it.

I should have fixed this problem.

I downloaded the latest daily build and i think the problem remains.

The scene you posted works fine here, check if you have correctly updated BlendLuxCore.

I can also still reproduce the problem with the latest sources (from auto build on Windows, self-compiled on Linux) with this scene: https://github.com/LuxCoreRender/BlendL ... issues/601 (after moving the domain cube a bit to the left).

I check last build (16 hours ago) and problems still there

It is working fine here:


and it wasn't before (the posted scene doesn't include smoke data so I'm using an homogeneous volume both cases).

What kind of result do you get ?
