Blender could not be launched.

Hi All,

When I open an existing project, or edit any .blend file within my project, Unity no longer imports .blend files. It errors out with the below error message.

Blender could not be launched.
Make sure that Blender is installed correctly and in your PATH.

I have made sure that "/Applications/Blender/blender.app/Contents/MacOS" is in my system PATH, so that when I simply type "blender" in terminal, it launches blender.

I only have 2.79b installed.

Any ideas?

 

I think this is the solution, https://forum.unity.com/threads/blender3d-io_scene_fbx-export_fbx-py-missing-removed.609877/

 

I have the same issue on linux manjaro, tried the workaround in the link, but it didn't work for me.
Did it work for you? Have you found another solution?

 

Just resolved this issue and this was one of the top search results when I was trying to find an answer - for me the solution was to right-click the Assets folder in the Project explorer and "Reimport All".

You of course have to have Blender installed correctly first! You should be able to type

blender

from the command line after logging out and logging back in (i.e., no intermediate commands run). Easy steps to do that are:

1. Uninstall any other versions of Blender you're using with

   sudo apt remove blender

   or

   sudo snap remove blender

2. Download the Blender tar file from the Blender website.
3. Extract the archive (I'm assuming to

   ~/Downloads/blender

   ) and put it in opt:

   1. sudo mkdir /opt/blender

   2. sudo cp -r ~/Downloads/blender /opt/blender

4. Make a *SYMBOLIC LINK* for your blender file:

   1. sudo ln -s /opt/blender/blender /usr/local/bin/blender

   2. NOTE: If you fail to use the -s option when making the link then you will make a HARD link and get the following error when you try to start blender:

      1. Fatal Python error: Py_Initialize: unable to load the file system codec
         
           File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/encodings/__init__.py", line 123
         
            raise CodecRegistryError,\
         
                                    ^
         
         SyntaxError: invalid syntax
         
         Illegal instruction: 4

5. At this point you should be able to start Blender from the command line.
6. Make a *SYMBOLIC LINK* for your blender.desktop file to be able to associate files with Blender:

   1. sudo ln -s /opt/blender/blender.desktop /usr/share/applications/blender.desktop

And again, once you've got Blender installed (correctly! lol) then, if you're still having issues with Unity stating "Blender could not be launched" then "Reimport All" in the Assets folder and you should be good to go after that!

 

Thank you very much @Chuck_S , reimport all fixed the issue for me

 

Or, here's a thought, keep blender files out of Assets/ and do all the exporting yourself so you have a modicum of control over the import process.
