Re: CPU + GPU

Nice! Yeah, I worked with Renderman for a while, which also has a bidirectional VCM engine. The results are quite nice, but once Blender 2.8 was released, Renderman support was left behind in Blender 2.79. Early 2021 there will be renewed Renderman support for Blender though, so Luxcore devs, just i...

Re: Sub-Surface Scattering

Bidir + Metropolis can't do SDS caustics, so at least the Caustics light cache would be an "advantage" for Path. I'm also with Sharly as in I don't even see any obvious SDS paths there. Maybe in the knife reflection onto the pumpkin-eye carving, but there is only diffuse lighting arriving there. Ye...

Re: Sub-Surface Scattering

I just figured to activate all settings that bring the Path engine closer to the Bidir + Mis result, for the best quality. But it turns out that Bidir + Mis still has the edge.

Re: CPU + GPU

I just discovered that Bidir + Metropolis has a noticeable advantage over Path + Sobol + Light Tracing + Photon GI Cache + Caustic Light Cache.

Would it be possible to accelerate Bidir + Metropolis using the GPU?

what purpose do you pursue by uploading such huge images to the forum?
Haha, no purpose. Just forgot to convert them to JPG. :)

It seems that all specular highlights are more prominent in the Bidir + Metropolis rendering, and the SSS also is a bit lighter, with a more gradual falloff.

Re: Sub-Surface Scattering

This is my final SSS material setup in the pumpkin scene: Halloween pumpkin by Metin Seven - Path and Sobol.png But, very interestingly... I decided to switch from Path + Sobol + Light Tracing + Photon GI Cache + Caustic Light Cache to Bidir + Metropolis, just to see if there would be a noticeable d...

Re: CPU + GPU

:)

I really like your render settings wizard approach to determine which settings are relevant. Maybe that could also be used for material creation, such as effective SSS?

Re: CPU + GPU

Aha, nice! :)

I guess indicating it as CPU + GPU in the 'Device' rollout would make that clear.

CPU + GPU

Hi, I was wondering: would a combined CPU + GPU power mode be possible to implement in Luxcore? Cycles has it for CUDA, but not for OptiX yet. It would be great if the CPU + GPU implementation would include smart render power distribution, to avoid the GPU being idle after finishing its tasks while ...

Re: Sub-Surface Scattering

That looks quite cool. I'll experiment with it, thanks.
