Importing vertices animation to Unity

Hi! I’m not sure if this is the right category… please correct me if I’m wrong!

Currently I’m building a VR project with trigger animations.

Using Blender, made animation using AnimAll, and keyed the vertices (put key to each vertices of bezier curve(no rigging)). First exported them to alembic and it seemed like it was working perfect, and I finished the vr project. Then discovered alembic doesn’t build in andriod…

I tried using glb after shape keying, VAT converter and a converter that converts alembic to meshes, but none of them were successful. (I might have been using them wrong… )

Does anyone know how to import animation keyed in vertices to Unity in different format than alembic?

Or know how to build alembic as android?? Help :sob:
