Also note: OCL too, takes foooreeveeer to compile now :shock: :P
But now you need to compile only once than is always cached (both for OpenCL and CUDA).

Still I cannot select devices in LuxCoreUI, same error as in BlendLuxCore:

Yes, I am aware of that... I just need to get used to it. :) None the less, great work, so thanks again.

Did you modify the .cfg file as mentioned?

That doesn't change anything, the Cornell file works the same with modification, once I try to change devices via UI editor there is an exit.

Cuda clearly works, sorting out devices not (yet) ;)

I should have fixed this problem, this is likely to have fixed BlendLuxCore problem too.

Sadly no, BlendLuxCore still gives an error.

Code: Select all

Traceback (most recent call last):

IDK, but I think something else also needs to be done on the plugin side to show options for CUDA device/ rendering.

In LuxCoreUI now everything works fine, two GPUs are listed as 4 devices, 2 x OCL + 2 x CUDA and can be selected and applied.
In BlendLuxCore I still get the same error that kintuX has posted above.

In BlendLuxCore, I use pyluxcore.GetOpenCLDeviceList(): https://github.com/LuxCoreRender/BlendL ... ncl.py#L77

Maybe only the GetOpenCLDeviceDescs() function was fixed?
This is the output of List() and Descs() compared:

Code: Select all

>>> pyluxcore.GetOpenCLDeviceList()
[('GeForce RTX 2080', 'OPENCL_GPU', 46, 1, 8589934592, 2147483648)]

>>> print(pyluxcore.GetOpenCLDeviceDescs())
opencl.device.0.platform.name = "NVIDIA Corporation
opencl.device.0.platform.version = "OpenCL 1.2 CUDA 11.0.126
opencl.device.0.name = "GeForce RTX 2080"
opencl.device.0.type = "OPENCL_GPU"
opencl.device.0.units = 46
opencl.device.0.clock = 1815
opencl.device.0.nativevectorwidthfloat = 1
opencl.device.0.maxmemory = 8589934592
opencl.device.0.maxmemoryallocsize = 2147483648
opencl.device.0.localmemory = 49152
opencl.device.0.constmemory = 65536
opencl.device.1.platform.name = "NVIDIA"
opencl.device.1.platform.version = "UNKNOWN"
opencl.device.1.name = "GeForce RTX 2080"
opencl.device.1.type = "CUDA_GPU"
opencl.device.1.units = 64
opencl.device.1.clock = 0
opencl.device.1.nativevectorwidthfloat = 1
opencl.device.1.maxmemory = 8589934592
opencl.device.1.maxmemoryallocsize = 18446744073709551615
opencl.device.1.localmemory = 0
opencl.device.1.constmemory = 0

I guess this needs an update? https://github.com/LuxCoreRender/LuxCor ... e.cpp#L121

It is a deprecated method: https://github.com/LuxCoreRender/LuxCor ... .cpp#L1752

I guess it is stil used in BlendLuxCore so I updated the code to support CUDA devices too but you should use the "GetOpenCLDeviceDescs()" in the future: https://github.com/LuxCoreRender/LuxCor ... .cpp#L1750
