Are you having trouble finding a way to keep the camera on your remote-controlled Sackbots in the LittleBigPlanet 2 BETA? This video teaches you not only how to keep the camera on the Sackbot you wish to track, but also how to have the camera revert to tracking your Sackboy as it normally does when you relinquish control of the Sackbot. It's nothing at all complex, and you have all the things you need right from the start.
NOTE: According to the BETA forums, MediaMolecule is planning to make this a LOT easier in the full game by having the camera default to following the Sackbot that you're controlling, but for now, this will suffice.
