No, the backfaces are always being drawn, because I though it would be a better default, since many model rely on that. You need to enable backface culling? Can I ask why?
But anyway, it would be definitely possible to add such option as an actor's property.

Hi! Yes I need don't draw backfaces like milkshape can do.. why? It's a secret  ;D
Really it's to do an experiment, basically i will implement a fake of "cartoon shadow" in my game, I do some test, but i need this option to do work perfectly..
If you add this option you make me very happy!!  :D

Backface is a term used in 3D graphics. 3D models are composed of triangles, sometimes known as "faces". And the faces have a front side and a back side (defined by the orientation of the vertices forming the trinagle). When rendering the 3D model, some programs can enable so-called "backface culling", which means the faces turned away from the camera aren't being drawn. This reduces the number of tringles needed to be displayed, but it can cause display artifacts on some models.
