Blender fracture and After Effects displacement map

The main problem when I tried to use After Affects displacement map with camera track was to position the object with the displacement effect.

After I use the camera track, I had to make a copy of the object, track null, 3D Tracker camera and then pre-compose them. If you pre-compose the object first and then copy the track null and 3D Tracker camera later, the position of the object and the displacement won't mach very well.

Still having some issues to use Blender displacement for texture.

Here the tutorial for the predator effect.
