PATHGPU with OpenCL and CUDA support

Can you run blender from terminal and post the output ?

Sorry for being so dense but I have no Idea how to use the terminal, there's zero UNIX knowledge.
If you post me a string I will type it in and we'll see what happens

I'm behind with the driver but it says "no newer driver available" ?

Found out how to do it (right-click on executable and choose: open with terminal)

Code: Select all

This is the CUDA installation:

Update:
I'm pretty sure your higher driver number results from CUDA 10.2 instead of 10.1 toolkit installed!
Going to try...

Version 418 seems compatible with 10.1 toolkit, see here:
https://docs.nvidia.com/cuda/cuda-toolk ... index.html
Versions are not shown for MacOS, but I guess major number cannot differ too much.

If you build with toolkit 10.2, you are probably going to need an updated driver.

[u3dreal]

I really will have check with my other mac. In theory it should work ... since i also just installed 10.1
I think i downgraded to 10.1 since Dade suggested that somewhere for compilation.

Nonsense.
CUDA 10.2 comes with a 440.xxx driver and then the add-on asks for the 10.1 lib, so no success.
But I cannot find where the 418.243 comes from?
In nVidia's archive the 418.163 is the highest available.

Restored to pre-cuda state, but kept the 10.1 dmg in case...

It is not a driver problem, the DLLs are included only in NVIDIA CUDA SDK so or they are included in BlendLuxCore (like on Windows) or you need to install CUDA SDK.

Yes, I have the SDK installed and the DLL (dylib on a Mac) is there but the add-on cannot find it on my machine but it does on u3dreal's machine...
If it is only this single library including it in BlendLuxCore OSX would be preferable than needing a 4GB SDK installation (smaller install is possible, but beyond my skills).

Why kernels always compiling on every new scene or when re-open Blender itself? It goesaround 5-10 minutes for compiling everytime

There are 2 DLLs used: nvrtc and nvrtc builtins.

I've problem with bump and HSV nodes.

I've opened this on BlendLuxCore but actually I don't know if it's something related more to LuxCore itself or Blender addon.

Anyway I report this.
