Render workbench on MacOS

[Brutha]

Hi All,

Has anyone had any success using the new render workbench on MacOS? I cannot seem to get any of the renderers working (macOS Catalina 10.15.7). I get the following:

- Appleseed continually asks permission to run libraries - you allow it and try again, and then it asks for another file, and finally says some files are damaged and won't open!

- I cannot compile the standalone Cycles renderer using their instructions - finally I get to:

Code: Select all

/Documents/cycles/src/render/colorspace.cpp:207:16: error: no member named 'applyRGB' in
      'OpenColorIO_v2_0::Processor'

- LuxCoreRender - I can run the app itself, but when I try rendering from FreeCAD I get the following. I am not sure what to select as the "CLI" file - either the app or something from the pyluxcore folder - there doesn't seem to be anything obvious. Either way I see:

Code: Select all

08:57:47  /Applications/LuxCore.app  -o "/var/folders/gc/kz6fvh1x6llcyhykn455_cjr0000gn/T/LuxcoreProjectkwv1z69b.cfg" -f "/var/folders/gc/kz6fvh1x6llcyhykn455_cjr0000gn/T/LuxcoreProject2c5ssfpe.scn"
08:57:47  LuxCore call failed: 'Permission denied'

- I tried a command line version of POVray from here http://megapov.inetart.net/povrayunoffi ... alpov.html. I get the following result in FreeCAD:

Code: Select all

09:18:16  Renderer command: /Applications/PovrayCommandLineMacV2/Povray37UnofficialMacCmd +P +A +W800 +H600 +O/var/folders/gc/kz6fvh1x6llcyhykn455_cjr0000gn/T/FreeCAD_Doc_2904492f-5719-4fc2-85ee-2d89a6ed1904_da39a3_41133/PovrayProject8b3kzgz_.png /var/folders/gc/kz6fvh1x6llcyhykn455_cjr0000gn/T/FreeCAD_Doc_2904492f-5719-4fc2-85ee-2d89a6ed1904_da39a3_41133/PovrayProject8b3kzgz_.pov
09:18:16  Running the Python command 'Render' failed:
Traceback (most recent call last):
  File "/Users/me/Library/Preferences/FreeCAD/Mod/Render/Render.py", line 1031, in Activated
    project.Proxy.render()
  File "/Users/me/Library/Preferences/FreeCAD/Mod/Render/Render.py", line 581, in render
    ImageGui.open(img)

Could not load image file

Of course, I guess none of the above are actually directly related to the workbench itself - but would be interested if anyone has seen the same and managed to get further!

Thanks,

Brutha

Hello,

I have just finished a write up of getting the render workbench working with cycles under macOS Big Sur.

Hopefully this might help you. I had the same issue you mentioned with cycles compilation. It is due to the fact that 2 days ago, the libs repository in SVN was updated to use a newer version of a dependency.

Anyhow... have a read here and I hope it helps:

Thanks @vectronic!

Sorry for the delay in replying, the day job got in the way for a bit there....

Yep, that was very helpful indeed, I was able to compile Cycles and I can now generate renders! Now I need to figure out how to save images where I want, and how to work with materials....

Cheers!

Brutha

Good to hear. Sounds like we’re now in the same place with materials

I have a problem with the Render workbench on my Mac too. Because the old post ist already very old and maybe many things have changed I post this question:

I a very new to the Render workbench in FreeCad so I tried to get it to work on my MacMini 14.3. I want to work with LuxCore so I have installed it on my machine. The standalone version seems to open. Unfortunately I can't find testfiles to have a look if the app works but I an assuming so.

In freeCAD i have to option to either choose a command (cli) path (whatever that should be) or I can direct him to the app itself. After testing that link I get a permission error.

What do I have to do to get the LuxCore implementation running?

Hello,
In 'LuxCoreUI path' field, you must enter the path to the executable. I'm not very knowledgeable about macOS, but '/Applications/LuxCore/LuxCore.app' does not sound like an executable - that could explain the 'Permission error', as you may be trying to execute a non-executable.
Having a look at https://github.com/LuxCoreRender/LuxCor ... -mac64.dmg, the executable should rather be named 'luxcoreui'. Perhaps you should search for such a file in your directories?

LuxCore.app is a package, right click with your mouse (or the equivalent on a touchpad) to get the context menu, choose the 2nd option. I have a dutch language version but it should be something like 'Show Package Content'.

In folder Contents/MacOS you'll find the 2 executables you are looking for.

So in the Render Workbench preferences you just add

<path were installed>/LuxCore.app/Contents/MacOS/<name of the program>

BUT! It crashes, at least on mine M1 Macbook when called from FreeCAD. Standalone it runs.

Yes, this solved the problem.

This should be written in the official description of the workbench.

Thanx!
