Importing .c4d files doesn't work at all

When I try to import a c4d file (through import asset, putting in asset folder, or dragging file to asset window), I get a white file icon and cannot drag the asset to the scene. i've tried with several versions of c4d - some old, some newer.

 

If you have Cinema 4D R18 installed and it's the default app for c4d files it won't work - the plugin that Unity installs only works with older versions. If you have R17 or earlier, make it the default app for c4d files and Unity should install the plugin and import c4d files ok.

A workaround is to manually export from C4D R18 to an .fbx file.

will it work any time soon for cinema 4d r20? using unity 2018.3

 

Please fix this for R20 or remove the feature from Unity.

 

I fully agree with Ruuds. Fix it or remove it.

 

Thanks for @greg-harding response but maybe you have administrator permission problem with Unity, you can fix it by this scenario :

1. For this to work, Unity Hub also has to run as Administrator.
   • Go to the Installation folder of UnityHub and open properties (Alt + Enter) of
     UnityHub.exe
   • Open the "Compatibility" tab, there you will find a checkbox
     Run as administrator
2. Now we can do the same for Unity.
   • Go to the "Editor" folder of the Unity installation you want to run as administrator.
   • Set Administrator settings for
     Unity.exe
     (see instructions above)
3. Fully exit Unity and Unity Hub
   
4. Restart Unity Hub, you should see the Windows dialogue for "Run as administrator"
5. Open a project using the Unity version you customized and Unity will have Admin permissions.
6. If you have problem with dropping objects to Unity, it happens when unity is running as admin, you can just copy and past your files directly using explorer instead of direct dropping.
