Unable to open Assets/xxxxx.fbx: Check external application preferences

$$anonymous$$assage? Heh, you mean message. There might be some settings in your modeling/animation software. What are you using to build your models?

I get same problem just today

and cannot open C# any longer and did "nothing" in preferenses or any read/ readonly files

can't open my C# that I used to open

So, you cant open a C# script in Unity? This isnt the same issue. The FBX import/export has nothing to do with Unity's C# script design. $$anonymous$$aybe reboot computer. If that doesnt work, reinstall Unity.

Hi Hardik,

Have you imported the .fbx file in to unity successfully?? I am using 3ds $$anonymous$$ax file to create .fbx file and I tried .max file also but failed to import.

If you are able to import please let me know.

Thanks, Purnah
