Which animation method to use in blender for later use in Unity? I'm trying to understand which animations on blender will be able to be animated in unity.

I have tried animating a net in such a way that when the ball hits it I will activate the animation to look realistic- I built a net, added a lattice modifier and animated with this lattice, but then I saw the posts about Unity not able to run them.

So figured I'll try Cloth animations but then I saw posts says Unity wont accept those animations also.

So, beside manually moving each individual vertex on my net, how can I animate that?
Unity supports rigged models.

You would need to learn how to parent armatures to your model and adding keyframes. There're many tutorials on this.
