Could of sworn this was done.
Someone suggested this not too long ago.The topic was horribly derailed, I do believe.
Even though this a great idea, is it really possible?
For what i know of, It is not possible.
It is possible... It wouldn't go as smoothly as you think, though. If the dimensions required a new datablock, then you would have to force all clients to re-download every datablock, which would cause the game to slow down slightly for certain players.
