Lets say, for a game, I want to make the side of a building, but its a seperate level, to its not INSIDE the house, you know? how do i do this? How can I edit whats inside? Thanks.
i think that you can ue another layer and put the stuff there
and if you need it you turn the layer on
I mean how to come about actually model the inside.
Maybe you can pick up some tips in yournamehere’s thread in the BGE forum: http://blenderartists.org/forum/showthread.php?t=122743
Don’t use separate layers, use separate scenes (at the top of the blender window). There is a “scene” actuator which gives you lots of options to deal with scene switching in-game.
