Re: Rendering

No, rendering speed depends on your scene configuration and the hardware you have available.
If your samples go up that slowly, your scene might be very hard to render, or your hardware is very slow. Can you give us more details about both?

Darkening the Diffuse and Absorption colors also doesn't work out.
Without access to the scene, it's just guessing, but have you tried lowering the absorption depth in the volume, instead of darkening the absorption color?

Re: Sub-Surface Scattering

Have you read this? https://wiki.luxcorerender.org/Subsurface_Scattering It explains some of the fundamental principles of using SSS in LuxCore. I used Random Walk SSS in Cycles, which is the same algorithm as LuxCore uses, unless I'm mistaking. This is correct. Slightly closer again, using a Hetero...

Re: Luxcore Optix crash investigation

Switching between GPU and CPU will require the renderconfig to be re-created, which is effectively the same as what's happening when the viewport is resized, so I guess it has the same underlying problem as this: https://github.com/LuxCoreRender/BlendLuxCore/issues/577 Which still needs to be invest...

Re: Studio-Scene now included with Luxrender

These are internal files used for asset thumbnail creation for the LuxCore Online Library.
They are not expected to work outside of their intended context.
You are probably calling the script from the wrong place.

Re: Little Octane adventure

It depends on what you are working on. For regular renders (model in Blender, render with Lux, done) I wouldn't want to miss filmic tonemapping of Blender's color management. However, if you want to render with LuxCore standalone externally, where you have no Blender color management (unless you fee...

Someone just pointed out to me that in LuxCore you're also expected to turn off Blender Color Management and activate it in the LuxCore camera. :D Didn't know that yet.
Not really, you can use Blender's color management and the LuxCore imagepipeline together.

Re: Lighting and PBR - The Parthenon

Your scattering scale was set to 0.
It is a multiplier for the scattering color:
total scattering = scattering color * scattering scale.
So setting it to 0 disables any scattering.

Just use a higher number like 0.1:

It crash repeatidly when switch and even if optix isn't use in addon pref.
Interesting, on my end, it doesn't crash at all when I disable OptiX viewport denoising.
