Hardware device selection string has the wrong length, must be 2 instead of 1 I am getting the same error, which is related to this property in the scene cfg file: opencl.devices.select As Dade explained in another post, with Cuda each Nvidia card is listed twice, both as OpenCL device and as Cuda ...

Re: Windows Build FAILED

Is there a way to have bare minimal files, since I really don't want to DL the whole 2.6 GB while needing maybe 10% of that... ? To me every Byte matters. ;) This should be close to the bare minimum, also without any documentation - 58 MB: cuda_10.1.243_win10_network.exe -s nvcc_10.1 cudart_10.1 nv...

Re: Windows Build FAILED

The problem was in this line that should make a script variable available to the rest of the pipeline job: echo "##vso[task.setvariable variable=cuda.path]%CUDA_PATH%" Apparently, in a CMD shell a bug causes a wrong output value, i.e. one double quote character at the end of the value, which then pr...

Re: Windows Build FAILED

Thank you for your feedback! :)
Indeed, there is something still to be fixed: gathering the required dll for for cuda version is not working at the moment, I am looking into that.
As soon as everything works, I will add it also to BlendLuxcore.

Re: PATHGPU with OpenCL and CUDA support

The result shouldn't change but the performance is usally measured with the samples/sec counter. Yes, I used the other value to exclude the native threads that I could not switch off. Now, without native threads and samples/sec as reference, I have 12% faster performance with OpenCL. I assume it is...

Re: PATHGPU with OpenCL and CUDA support

P.S. are you selecting only the CUDA device, right ? NVIDIA GPUs are now listed 2 times, one as OpenCL device and one as CUDA. I'm also doing the test with 0 CPU threads. Yes, I tried selecting different devices with e.g. opencl.devices.select = 001 The speed is smaller when CUDAIntersect is used a...
