I checked and Custom Split Normals was already added to the mesh. I clear it and the artefacts don't show up again even tough I add the Custom Split Normals back :shock: . Any explanation? :geek: Thank you all for all your tips. Glad we could help! I have observed that with custom split normals, th...

I think, like you, I'll settle for the :2 option for the moment. The lag is not so bad as to prevent me from working in the background, and you have a good indicator for a completed build when the lag is gone

Thanks for the help, now I was able to improve performance and also understand the relevant part of the script. (one problem in my earlier attempts was that - working mostly with python - I misinterpreted the brackets in the comment "/cpucount[:n] specifies ..." :lol: ) The scaling of msbu...

One more idea: Do you use Blenders custom split normals in your mesh?
LuxCore supports it only since v2.4.I don't think it would explain all of your problems, but if not you could try using them and see if that fixes those spots.

if I set something like set CPUCOUNT=4, it just aborts after a few seconds. would that be correct syntax though? I can't find anything about this via google.

Digging out this old thread as its the only reference I found...
Just noticed myself that BlendLux doesn't export alpha. Its indeed easy to changeby adding one letter in the cfg, but perhaps you want to reconsider enabling it in the addon?

Is there a way to limit the number of CPU threads during compilation?
Currently, it makes the system quite unresponsive for a few minutes. I can live with 8 min compile time instead of 5, if I can use the computer in the meanwhile.

Tried standalone, same result.
Also tried setting the cpu thread count to 0. Again, no change to the shadow, only the reflection by the mirror cube disappears (as I would expect)

Here is a side-by-side comparison. Still a tiny bit of color difference of the background plane but I think we can agree the shadow difference goes beyond that. I could not replicate it (from within Belnder) with some settings variations (cpu/OCL, light tracing on/off, cache on/off) compare.png I wi...

One thing I found while exporting from Blender is that the exported camera FOV does not take into account the sensor fit method, which initially resulted in a much smaller FOV than anticipated This seems to be normal behaviour of LuxcoreUI specifically. Acutally had this question on ym mind for a w...
