Is it possible to Alter gravity so that you could say walk around in a giant cylinder and go in a circle in the Y axis? For those of you who understand i was thinking of trying to make something like the Rama craft from Arthur C Clarke's series.

Might wanna ask Fliggerty that as it might require MWSE and he's the creator of that tool.

With some tricky scripting, it might be possible. Not necessarily easy, and there are a few issues to consider. I doubt you could rotate the player. In fact, it might be easier to watch for the player to move, and every frame take the delta (distance moved) and center the player and move the cylinder instead. That has its own set of issues, but might be simpler if you set things up just right.
