How to bend a chain

Hello.
I need to make an animation of the chain. I have the model made in 3ds MAX. The chain is bent thanks to the Path Deform modifier and animated. When I export the file thanks to DATASMITH. The chain does not move. I can’t use bones because there are too many elements .
I tried Vertex Animation but the bitmap is too big ( the animation has 5000 frames ). I also tried Alembic with no effect.

I decided that you have to make the chain in Unreal. I am a beginner and I don’t know how to create a chain that moves along a path.

You could recreate this with a spline and spline mesh component for the chain.
