Hey everyone,
I’d like to share a small Unity package I made with you, called Geometry Sequence Player. This package allows you to bring vertex animations made in Blender to Unity. Here for example I used it to playback a procedural Geometry Nodes animation and a fluid simulation in Unity:
To bring your animation to Unity, you simply need to export it as a sequence (one file per frame), and convert it with a little tool that is included. The package supports mesh and pointcloud sequences, so at it’s core it is similar to using the Alembic format. But additionally it supports per frame textures, mobile / XR devices, and is not limited to a specific file format.
The package is free and open source for non-commercial use. If you’re interested in trying it out, you can head over to our Github page. If you want to support our development, or use the package commercially, you can also grab a copy in the Unity Asset Store 
In case you have used the package, I’m very interested to hear how it worked out for you and if there are any improvements or features you’d like to see!
