I guess the hoster throttles the download rate?

I'm not going to download this file for 3 hours.
Can you strip it down so it is smaller, but still shows the problem?

You can change the renderengine.type here: https://github.com/LuxCoreRender/BlendLuxCore/blob/65b5b75b20725f6f643943d88b3bf1f5b5d59e60/export/config.py#L52 You might want to also set some of the other properties of bidirvm: https://wiki.luxcorerender.org/LuxCore_SDL_Reference_Manual_v2.3#Experimenta...

The luxcore mirror material is just simply an ideal mirror, i.e. 100% reflective. Not sure how metal is defined internally. You can always try mixing mirror with perfect matte black, if you want to play around with tuning reflectivity. Changing the reflection color of the mirror material should be ...

There is now a script to convert scenes from v2.2 or before to v2.3, since we had some changes that broke backwards compatibility (see the release logs of v2.3 for details). You can run the converter with the big button in the new LuxCore Tools panel in the render properties. Note that if your v2.2 ...

Something like that, yes.
But maybe that changes in the next competition, since I picked "Caustics" as the theme

It depends on the reflectivity of the mirror, just do some tests with higher/lower path depths.

denoised.jpg To test Lux v2.3, I created a small scene. Rendered on RTX 2080 in 30 min, denoised with OIDN. All textures are procedural, not a single image texture was used. The clouds were created with a heterogeneous volume with textured scattering. This entry won first place in the BlenderArtist...
