Hi Felix,

Since the move of the objects is based on the same delay, you can remove the setup of the Fields in the Vertex Map and replace it with a Linear field. This will bake just fine. While also allowing for an easier adjustment of the fade based on the Linear field adjustment options.

The colors of the fracture setup are based on Phong angles of 180; the Alembic is baking a Normal Tag for the Objects as they are. Hence, the color bleeding of the Fracture Setup is different. I ignored the Bevel here (as before). I suggest directly putting that model into the object so the point number doesn't change. I also placed all objects equally under the Fracture Object; why group things and separate them on every frame? Perhaps your full setup requires it, but the provided file gave me no hints.
Perhaps set up a texture for this "Vignetting effect" instead of a phone angle of 180º.

All the best
