Mixing shadowcatcher planes in 3d invigorator with 3d reflector.

I've created a 3D plane inside Invigorator to use as a shadow-catcher for a 3D model. This works perfectly. My problem is that I'd also like to use 3D Reflector to make a reflection for the model as well, so I create a After Effects solid, make it a 3D layer and then position it in the same 3D space as the Invigorator shadow-catcher plane is. Unfortunately, even though the only visible aspect of the Invigorator 3D shadow-catcher plane are the shadows, the entire 3D reflector effect disappears. I am assuming that's it's not possible to have 3D Reflector and a shadow-catcher plane working together in the same 3D space?
