LuxCoreRender Forums

I've encountered this too:

As I said, I cannot test it since the current LuxCoreUI doesn't work on my Mac.

I can only quote what was said in the link I posted above:

5) once you have all maps, you can load "render-bakedallobjects.cfg" in luxcoreui to do the rendering with the created bake maps (i.e. with only one ray per ...

Please do not replace emitter objects with different kinds of lights, try to keep it as it.

BlendLuxCore warning:
The scene contains a lot of light sources (1111), performance might suffer (each triangle of a meshlight counts as a separate light)
I don't know how light tracing actually works ...

Thanks @daros & @bartek_zgo for your contribution, very much appretiated!

You should open an issue on GitHub about this bug.

Good Job, the interior animation at 32sp looks great

About the issue with the complex glass scene I have no clue

I use Luxcore from within our own inhouse app (felixrender)

Oh I see.
I had another go using BiDir this time and got problems with the reflections of the wall caustics on the floor.
These are SDG-paths (specular-diffuse-glossy) and BiDir cannot resolve them in 128 samples so that it looks stable ...

What is to be animated, cam, spotlight or the sculpt?
You provide no blend but an object file, so the materials have to be guessed.

In case the lights are not animated, it should work simply with Indirect Light Cache.
I'm assuming the walls are matte but the floor is glossy and are excluding it ...

LuxCore has several unique render methods like light tracing and Metropolis sampling that should be utilised in more ways.

Currently there is one hybrid render engine that does light tracing for caustics only on CPU and path tracing independently on the GPU and then adds both results.

In earlier ...
