I have extended the FAQ with a few new topics: https://wiki.luxcorerender.org/BlendLuxCore_FAQ 1.2 Is there something like Cycles' Layer Weight/Fresnel/Facing node in LuxCore? 1.3 Can Cycles materials be used in BlendLuxCore? 1.4 Can 2D/3D mapping be driven by textures in LuxCore? 1.5 What can be do...

You're probably looking for this button:

Ah, ok, si I assume that refers to the normals modifiers and the baked normals into the mesh, but the normal smoothing with angle works ok and does not affect, right? Yes, I mean the feature that is labeled "custom split normals" here: https://docs.blender.org/manual/en/latest/modeling/meshes/struc...

What versions do support that and what version don’t? Currently, fast export is supported for 2.82.7 and 2.83.* This can be checked here: https://github.com/LuxCoreRender/BlendLuxCore/blob/master/export/mesh_converter.py#L9 Also could be great to be able to enable/disable that export if it slows do...

I have implemented a Python fallback for custom normal export, which is used if the fast C++ export is not supported for a Blender version.
This means custom normals will now always be supported.

I think the leaves looked fine in the first version. I wouldn't expect to see much translucency when the light is above the leaves.
In the new version, they appear a bit dry.

Limited noise depth to 25, with a soft limit of 10 in the Blender addon.

Since fscale is multiplied by 2 each loop iteration, it just gets very big. This causes the call of noisefunc() to return NAN at around iteration 29. When x, y, z are bigger values, maybe even sooner. I don't know how/if the Blender developers dealt with this. I would suggest to lower the max. noise...

Could the input be restricted to a maximum of 29?

It should be max. 30 and the other bug causing it to fail at 29 should be found and fixed.

In the Blender Marble Texture, the Noise depth appears to be doing some strange stuff at a value of 29 and above. (attached files). I suspect the problem is here: https://github.com/LuxCoreRender/LuxCore/blob/a218d58c1de9c1fc7fd5e10da9ef8070559f3be2/src/slg/textures/blender_noiselib.cpp#L1399 (the ...
