Unity suddenly unable to import FBX from Blender correctly.

Hello All,

I recently tried to update my player model the same way I have been for months. (Export from blender and FBX that over rides the asset within the unity folder) This has worked flawlessly for months…

Now upon import I receive the following Error:

NullReferenceException: Object reference not set to an instance of an object
UnityEditor.ModelImporterClipEditor.AnimationClipGUI () (at <6f28216fea9f453abf2e05b770ed3ee4>:0)

I’ve tried using older working Blender Files as well to no avail.

Anyone else encountering this problem?

Best,

I noticed that Unity 2019.3 doesn’t “understand” fbx which contain several animations. Previously, they were converted to clips.
If you create fbx with one animation, there will be no errors in Unity.
