So I made a VR animation in Quill. I exported it as an alembic file. Imported it in Unity through an alembic import package. Made a timeline and if I hit play I can see the animation playing and behaving as I would expect (I can also see it with my VR Quest 2 plugged into my Pc). The problem is when I tried to export the .apk form Unity. I just cannot see that file at all.. all the other files that I made from Blender are working, but that alembic one from Quill is not there. Why? Why does it work on unity, on my pc, but doesn't when I export it as an .apk and install it on my Quest 2?
