I keep getting LuxCoreUI crash when rendering the LuxMark-Hotel scene on the GTX 970: it exits without specific messages when the render is about to start. Here is the output: F:\Ale\Devel\LuxCoreRender\LuxCoreTestScenes>C:\Users\Alessandro\Desktop\luxcorerender-latest-win64\luxcoreui.exe scenes\Lux...

While thinking how to do this, as per B.Y.O.B.'s suggestion, I ended up thinking that it would probably be a (partial) duplicate of this: https://github.com/LuxCoreRender/LuxCore/commits/master I have added this link in the "latest" release description: https://github.com/LuxCoreRender/Lux...

Since our Optix/RTX implementation needs Cuda 11, should we update the nvrtc and nvrtc-builtins libraries to v11? At the moment we are distributing v10.1, at least in Windows packages. I was testing if the GTX970 + driver v451.67 is working with Optix and had some strange behaviour (i.e. LuxCoreUI s...

@Acasta69, should we switch to VisualStudio 2019 ? I hate to touch stuff that works but is 2017 still available ? I hate that too... We have to switch sooner or later, it's in my to-do list, but honestly with not so high priority. As for availability, it is more and more difficult to access older v...

Numpy is another package needed by luxcore, you can install it with

Now there is a single, unified executable that can detect if OpenCL or Cuda are present and use them. If none of the two is detected, CPU only is used.

Delete all kernel cache files ( :?: where are these located on a Windows 10 Pro :?: ) Cached kernel locations should be as follows on Windows (I have the Home edition, but I think it does not matter for this file location): LuxCore 2.3: C:\Users\<username>\AppData\Local\Temp\kernel_cache For v2.4 t...

I saw this in Matt Pharr's blog:
Accurate Differences of Products with Kahan's Algorithm

Is it something we could take benefit of, or would it just make LuxCore slower
(Or maybe the problem is already worked around differently in LuxCore?)

Edit: oh, I see, you probably mean the missing CUDA DLLs. Actually I'm not sure about that as well. Where is this error ? There are no cuda libs in the package created by LuxCore Azure .. @Dade, how does this work on Linux? Isn't it necessary to distribute the Nvidia nvrtc and nvrtc-builtins DLLs a...

Hmm there are some errors on linux side ... but yes it builds but only linux-opencl .. Do you mean this one? https://dev.azure.com/LuxCoreRender/LuxCoreRender/_build/results?buildId=2251&view=logs&j=f2ac135a-940d-50ae-9789-b012bc1d7b2f&t=314e78b1-3837-5838-9aba-05fadf26a591&l=429 Ye...
