Adam,
I was watching a tutorial (older v9) and they instantly had 6 faces in the object tree under the cube parent object. The teacher did not show how or eplain, it just popped on after making the cube an editable object. This was Cineversity tutorial.
I tried your way in r10 and it appears to take many steps to get all six sides separated and listed on the object manager. Was there possibly an old plugin or something they were using?
Do you know why I now get all soft edge transitions when beveling the cube faces (I see this on text also)? I thought v9 always gave me sharp edge transitions on beveling. All I can figure out is to always adjust the phong tag down in the angle. Sorry, I am not an expert in this app, but learning quickly.
