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?

How is process of using a procedural map when rendering? Is it baked to an image?
No, procedural textures are not baked to images. They don't have a resolution.

Re: color conversion from standard rgb 0-255 to luxcore 0-1

You will need to set the gamma to 1 for such "non-color" data textures. Same for bump maps, roughness maps etc.

Re: Where the bump gets strange

If I take the baked map into the lux shader, it results in a good bump, too. But if i try to drive the bump by a procedural map, the bump doesn't appear. Then I guess the problem is somehow caused by the procedural texture you use in LuxCore. In the screenshot above you used fBM. Are you aware that...
