Meta Building Blocks and issues with controllers

Does anyone like those building blocks?

I think they suck. I would much rather got the old prefabs back.

Anyway, building blocks camera rig and controllers seem not to work, at least deving over Link. I just get all the controller modles (Rift upwards) active and button animation not playing.
