Break a Glass using Meta SDK

You'll first need to create a fractured version of your glass in a 3D package like Blender (https://www.youtube.com/watch?v=S1UvEd1xkco) Add the rigidbody and mesh collider for each piece as shown in that video, but you'll probably want to to a runtime swap between the original model (prefab) and the fractured (prefab), perhaps when the glass hits the floor, or whatever is appropriate for your scene. So perhaps start with the unbroken glass and attach a script to it that has an OnCollision method (https://www.youtube.com/watch?v=QRp4V1JTZnM) then when that's detected, instantiate the fractured prefab and disable the original glass.
