Yes, I could add also glossy nearly-specular materials to the set of materials supported by the cache.

That would be very welcome, for glossy, metal and the upcoming principled materials.

I'm working on a "Split RGB" texture.

could you share the node setup please?

Here you go:

And here is the Blender file:

Expose uvmapping3d (available in the 3D mapping node, can be used to map procedural 3D textures with a UV mapping)

I could finally test it and I love it!

Here I used only procedural textures, and - as expected - the patterns nicely follow the shape of the leaves:

Thank you!

If BIDIRCPU+Sobol is faster than BIDIRCPU+Metropolis, you are probably rendering a scene that will converge even faster with PATHCPU+Sobol

Bidir is often needed when the light is hard to reach (like the lamp scene with the lampshade), but shadow areas still converge faster with sobol. IMHO

...the only real/effective adaptive sampler for BiDir is Metropolis because Adaptive Sobol can work only on eye paths while light paths are unaffected. ... Thank you for your advice! However in my (not too extensive) experience, it's harder to get noise-free result with metropolis than with sobol (...

If I'm right, BlendLuxCore still didn't catch up with the new adaptive sampling parameters, so I used LuxCore UI. I've found the parameters in the code: film.noiseestimation.warmup and film.noiseestimation.step . Blender's color management (Filmic) is really missing here, so these images don't look ...

Great news, thank you for your efforts!

Would you be able to redo this test?

I'll test it tomorrow.

Besides, keep in mind that the tonemap you chose is considered during the noise estimation...

I think this is a good direction and it'll give the best results in most cases.

Here's the file with Null (Transparent) material set to the lamp shade.

Note: as an end user, I would wait a few days before trying to test this new stuff, it's not in a usable state yet. As alpistinho said, the Blender addon was not updated to use the new properties yet, for example.

3d is just a hobby for me, and I try to help you as much as I can.
