@Dade, I have simplified the scene a bit, can you do a test with this?

Doesn't the CC-BY-SA license text already explain everything?

We could try to mimic the SSS behaviour in the Cycles principled material: https://docs.blender.org/manual/en/dev/render/shader_nodes/shader/principled.html Take special note of the Subsurface description ("Mix between diffuse and subsurface scattering. Rather than being a simple mix between Diffuse...

So I want to repeat this image 2 times in vertical. Than we put a ground surface, and don't care about the sky under the ground. Is it possible to do this?

What about doing it in an image editing program? Or is memory usage a concern?

I can also still reproduce the problem with the latest sources (from auto build on Windows, self-compiled on Linux) with this scene: https://github.com/LuxCoreRender/BlendL ... issues/601 (after moving the domain cube a bit to the left).

To try and get more light, here's a test with more bounces, and Diffuse shader's diffuse color with color value=1.2 (living dangerously ), not sure it is taken in account. Color values in the materials are clamped to (0, 1): https://github.com/LuxCoreRender/LuxCore/blob/92eac130fac12026470fec1c5013...

Is there any particular reason why 2.4 would measure less Samples/Sec than 2.3 with my hardware?

See https://wiki.luxcorerender.org/LuxCoreR ... ce_on_GPUs

I forgot about that one. Added.

Ok, I have added the "Sampling Distance" parameter to the bump node. The tooltip description is Distance to use when picking two points on the surface for bump gradient calculation. Use smaller values if procedural bump textures with very fine details don't show a bump effect. Note: does not affect ...

The default sampling distance is 0.001 (1 mm), smaller value should be used if the bump (procedural) texture has smaller details (like in the case above). In my tests it seems like just using a lower default value in all cases could be a solution. But I guess the default was chosen higher for a rea...
