Game Level Builder
Game Level Builder 3.0 (GLB3) - is a toolset for making convex e.g. (bsp ruled) based levels for games using discreet's 3ds maxâ„¢ and gmaxâ„¢. The main difference between GLB and all of the standard convex based level editors is that GLB's main system for modelling is not based from boxes which are hollowed or carved (CSG subtracted). GLB allows you to simply draw walls and click in doors - windows and floors. GLB3 can help you create levels faster than any other tool on the market. Create Stairs in seconds - entire buildings in minutes and complete levels in a few hours.

Using GLB's floor tool and invisible walls - you can create almost anything you want faster and easier than with standard CSG methods. This method of modelling is similar to Surface Tools in max - i.e. spline modelling - except instead of the SplineShape being limited to triangles and rectangles - the splines can simply outline the required shape. Thus eliminating the need for placing a whole lot of splines to define a relatively simple object.
