LuxCoreRender Forums

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 ...

- Expose russian roulette parameter (minimum light bounce) like in Cycles and LuxCoreUI.

Yes, seconded.
There is already a GitHub branch and also some discussion.
Another feature that was included (maybe not finished) but never exposed.

In the mean time v2.10.0a1 is out and works well on my MacBook.

- Upgrade the Luxcore fbm texture node to match the current cycles noise node with three color channels, lacunarity, distortion etc.

Good to know it will be accounted for, thanks!

- faster rough glass shader. When adding roughness to current LuxCore glass, it renders slower and the result is darker unlike cycles glass. Could eventually be combined with Disney 2015 shader which contains refraction and is already on the list.

- There is a BakeCPU engine (including lightmaps) that Dade finalized in LuxCore but it was never exposed in Blender. See also here .

- Path Guiding. It is currently developed by Intel and available in Cycles on CPU only. It was voted #4 in the last poll . The Intel version does online learning ...

There is a new release of BlendLuxCore 2.9 which now contains Mac versions for Intel and ARM!
On my MacBook M3 on Blender 4.3 it works stable and while BiDir Render speed has improved, PathOCL on GPU is slower than my main installation of LuxCore 2.61 on Blender 3.1.

I recommend to test this new ...

Happy New Year to everyone, and it comes with a new caustic cube animation, enjoy!
