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. :)

:shock:
Wow look gorgeous ! Definitely great news. Now it s possible to make easy spacex rocket sim or Car tyres burnout.

Yes, I saw that yesterday during testing. I can change that, too, but not from work.

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

There is also emission :idea:

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" to "fire+smoke"
  • select the larger domain cube, go to the material tab, press the "Fire and Smoke" button
  • render, optionally open node editor and edit material/volume settings
This is how it currently looks like:

Is it possible to integrate Random Walk SSS and Micropolygon Displacement like Cycles did?

It is like 7 years we do Random Walk SSS :D It is the only way we have always rendered volumes. Lux, by design, usually supports only solutions leading to the "ground true" (i.e. unbiased) and avoids approximations and/or tricks.

We had the support for displacement in the old Lux but it was insanely slow. However yes, we should add the support in the future, it is something useful.

1. So, how can I make SSS effect using Random walk method? Any tut for it?
2. When is it come? Any date?

This is a video recorded with the old Blender exporter and LuxCore but the concepts are the same: https://www.youtube.com/watch?v=DDqXv6gu3ts

Not in v2.0, may be in v2.1 but I have some stuff I consider more important (like light cache and denoiser) in my personal TODO list.
