Re: LuxCoreRender v2.4beta1 released

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.

Re: AttributeError: 'LuxCoreScene' object has no attribute 'opencl'

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...

Accurate differences of products with floats

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?)

Re: Unified executable (for CPU-only, OpenCL and CUDA)

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...

Re: Unified executable (for CPU-only, OpenCL and CUDA)

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 Yes, the "linux64-...

I should have now updated everything and, yes, neither "opencl" nor "cuda" in the directory name are required anymore.
I have updated the Azure pipeline files.
BlendLuxCore seems already ok, no modification necessary.

Re: Unified executable (for CPU-only, OpenCL and CUDA)

No access to secure file for me .. should i merge ? otherwise no check possible. maybe you can check .. For increased security, secure files and secret variables are never accessible to pull requests coming from forks. If you prefer not to act directly on the master branch, you could create another...

Re: Unified executable (for CPU-only, OpenCL and CUDA)

I have updated the azure pipeline files for Windows and it's running now. I'll check the binaries as soon as they are available. About Linux: is it enough to build only the version with neither "opencl" nor "cuda" in the directory name? Or do you need to modify the build scripts in the "LinuxCompile...

Re: Unified executable (for CPU-only, OpenCL and CUDA)

Defining LUXRAYS_DISABLE_CUDA and LUXRAYS_DISABLE_OPENCL seems to have no effect: LuxCoreUI still allows to choose OCL render engines. I'll try to check why this happens. Yes but it should have no device available at all for the rendering. I guess it could be removed from the menu too. I updated Lu...

Re: Unified executable (for CPU-only, OpenCL and CUDA)

What is so bad about that ? On Linux you can use NVIDIA and AMD GPU together ... i plan to do that ... :D What dlls do you need to copy ?? Well, nothing so bad I guess... ;) Only, it's not the expected behaviour... The needed DLLs on Windows are nvrtc64_101_0.dll and nvrtc-builtins64_101.dll . They...
