This is somewhat expected from Sobol sampler, it is noise under another form. Regular patterns Vs. random noise: in both case you need more samples for a clean image. I also observe obvious patterns that don't disappear for a long time in some renderings. See the attached image for example. If you ...

By the way, variance clamping is the one I meant above. There is no other clamping anymore.
I guess by "instance support" you mean dupliverts/particles etc.? It's under construction.

When starting the rendering, there is always a 2second lag in the test scene I used (in the video below). Does the addon export all geometry every time? I couldn't find the older option to only export geometry that was not already exported (available in older luxcore versions). See this issue: http...

I think you don't even need the alpha=0 border.
Just set the node with alpha mode to wrap to black and you're done.

You can set the border pixels to alpha=0 and use this node setup:

I'm sure Dade will make a big post about it when it's finished, explaining everything.

I hope this image illustrates my idea.

Yes. That's why I said that all border pixels have to have the color that you want to be extended.

Here's the BlendLuxCore issue: https://github.com/LuxCoreRender/BlendLuxCore/issues/16 There are also other weird things going on, like that the object seems to travel further than it's start and end points with long shutter values. I think I'll write some unit tests, maybe that will help me sort it...

Well it would behave the same way like the Blender stamp, which is also "baked into the image".
You can switch it off, of course.
