Blender to Unity: Animation with multiple objects

I am trying to import an animation from Blender to Unity.
It's a physics simulation with around 50 objects. I used Blender to bake the animation to keyframes.

(blender render)

When imported into Unity, about 2000 animation clips are generated (see screenshot below). It takes quite some time until the whole thing is imported. Is there any way to fix this multiplication of clips?
(A similar problem was mentioned in this thread.)

And in general: Is it even possible to import an animation with this many objects to Unity and have it controlled by a single animation controller?

 

I did some more research: exporting to Alembic did the trick.
For the import you need to activate the Alembic package in Unity's Package Manager.

 

I just noticed that the Alembic package is not supported on iOS.
So I am back at my original problem: How to import an animation with this many objects?

Any suggestions?

 

Look for texture driven animation

 

Did you find solution?

 

you could try using alembic to VAT after importing, this will enable ir for IOS
