@Dade: can we do something about this in the addon or in LuxCore? It is like having 2 coincident planes and having some ray hitting one or the other. It is a numerical precision problem. I think the only transparent (for the user) solution is a specific trick in the exporter or LuxCore adding an ep...

Can you post the test scene ?

There are many factors that could influence the outcome (like the Russian Roulette settings, etc.). It is hard to say looking only to the rendering. Anyway the BiDir result looks wrong.

Also i want to ask if the clamp wrap in the imagemap node works?
I tried an example but it didn't work.

Yes, I checked and it should be in v2.0Alpha1 (alpha1 has been released 7 days ago while the the wrap code has been written 12 days ago). B.Y.O.B, does it work for you ?

@Dade: I'm trying to use SetFromString() on a properties object, but it's failing with RuntimeError: Syntax error in a Properties at line 2 The spaces/tabs before the "#' char. Comments must have a "#" as first char of the line at the moment. I will add a trim() to let the parser be a bit more flex...

Just turn arround the net and saw some benchs of Titan V on some workstation software. This big chips is really strong. look what it scored with Luxmark 3.1 : It is the first "real" GPU upgrade since the HD7970. The performance are spectacular ... unfortunately, the price is too but I guess there w...

BTW, LuxCoreUI has a simple procedure to estimate reasonable value for variance clamping: https://github.com/LuxCoreRender/LuxCore/blob/51fb3632cb0f205467bae90e35a17d7b172f399c/samples/luxcoreui/renderenginewindow.cpp#L116 It is simply the average luminance of the rendered image multiplied * 10 (and...

I should have fixed the problem (pull both LuxCore and BlendLuxCore).

I have to apply the worldscale of Blender, otherwise the camera is in the wrong place.
However I could undo the scale.

But was that the problem you were talking about ? Or is there something else ?

However, something weird is still going on - do you have an idea what could be wrong? Only the camera is moving here. I'm not sure if this is the problem you are talking about but the camera transformations include some kind of scale. It something strange and unexpected, as result the rays to trace...

Very cool. I implemented support for it in the dupli_export branch: https://github.com/LuxCoreRender/BlendLuxCore/commit/6f749a9b270856a9adbd83701adaa589341729f6 Results (particle export only, 10000 particles): Previous export: 4.13 seconds New export: 0.37 seconds By the way: always funny when Ble...
