Hi.
I need a little help here with open cl devices.
i use select devices like this "opencl.devices.select = 11\n"); and it work perfectly on one of my machine with AMD Gpu but when i used it on another machine with nvidia Gpu it show an error "OpenCL device selection string has the wrong length, must be 1 instead of 2" and as you can see clearly luxcore detect just one openCl device.
I even try to use GetOpenCLDeviceDescs(); to detect Gpus but got no where as i can see first and secound device in return.
what's the problem here ?

Re: MaxLuxCore - 3ds Max Integration for LuxCore
Can you post the complete output of clinfo ? It is usually included with OpenCL drivers otherwise it should be available here: https://github.com/Oblomov/clinfo (https://ci.appveyor.com/api/projects/ob ... orm%3a+x64)
You could have a second Intel OpenCL platform without devices

Re: MaxLuxCore - 3ds Max Integration for LuxCore
It looks ok.
Are you using some other "opencl.*" property for LuxCore ? Like the one to explicit select the platform or to use only GPUs or CPUs devices. Can you run LuxMark and LuxCoreUI to check how many devices they see ? In LuxCoreUI there is a menu Windows => OpenCL device editor option to check the devices available.
Re: MaxLuxCore - 3ds Max Integration for LuxCore
Interesting, i ran luxmark and i can see only one device in there too.

Re: MaxLuxCore - 3ds Max Integration for LuxCore
Sometime, Windows updates break driver installation, the Intel OpenCL platoform may be broken, you could try to re-install, it usually fixes the problem.
Re: MaxLuxCore - 3ds Max Integration for LuxCore
My problem is Gpu openCl, Cpu openCl works perfect.
Also i reinstall Gpu driver multiple times.

Re: MaxLuxCore - 3ds Max Integration for LuxCore
I reinstall GPU driver and run some other applications to see if openCl works or not and it's working.
But with luxcore same as past, not even detected !

Re: MaxLuxCore - 3ds Max Integration for LuxCore
I have sincerely no idea, the fact that LuxMark doesn't recognize your Nvidia platform is very strange and it is the same, many years old, executable that has been tested on hundred of thousands of OpenCL installations.
I would try to remove the Intel OpenCL, than re-install Nvidia drivers and check how LuxMark work at that point.
