Re: LuxCore Online Library (LOL)

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

Re: Disney BRDF material

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?

Re: Volume Intersect Problem

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).

Re: Specular reflection vs diffuse reflection.

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?

Re: Where the bump gets strange

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 ...

Re: Where the bump gets strange

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...

Re: Where the bump gets strange

This parameter is not yet exposed in the addon.
What would be good min/max limits for it, and what could be a good descriptive tooltip text?
