Thanks everyone for your comments! A frame took 8.5 min to render (2x RTX2070, indirect cache on the wall material, no light tracing), 1000 frames were rendered. I tried filmic tonemapping but it looked somewhat dull, the burned top is something I would have gotten from a real live shot with a digit...

Old project rerendered, sculpts made with TopMod.

Edit: Updated the file because somehow the frames were decentered in the first upload.

b) Caustics almost never work on transparent surfaces. I'd assume that's how it is meant to be, the glass shader emulates an "ideal" material and that would indeed not receive caustics. In reality glass is never perfect and clean, those imperfections could receive caustics. Therefore you ...

I remember there is also a light map option?
This should be great for render speedup with less bias than indirect cache.
Except from gltf export there could be a normal render result (from bakecpu engine) that can be composed/denoised like any other render for reuse in production rendering.

Yes please
Thanks for your efforts!

changing the glossiness thresholds It seems the threshold does not distinguish between the diffuse and the glossy part of the glossy shader. When I exclude a material via threshold it does not receive any caustics, neither glossy nor diffuse. The glossy shaders are special because they can produce ...

The current hybrid engine with SDS-cache is very stable and especially with the new albedo transmit denoising great for animation . But once I choose a glossy ground material flickering occurs and ruins the animation. After closer inspection I think the cause is "SGS-paths" (specular-gloss...

i wonder how they achieve the sds caustic in the clay mirror scene you posted. Assuming they use photon mapping SDS caustics are already included. It is LuxCore light tracing (Path or BiDir) that cannot do SDS by design and needs additional caching. LuxCore revolving cache is not bad IMHO but it ne...

Indeed, now that LuxCore has adopted CUDA/Optix and utilizes RTX-cores it is time to think about how to make use of all those tensor cores as well.
Metropolis sampling is not working well on GPUs, a tensor powered neural sampling would be very welcome.

Could the SDS-cache for BiDir be exposed in BlendLuxCore, please?
