The DCOL Editor is a simple tool that allows users to edit the properties dynamic collision object files with the .DCOL extension.
The executable for this tool is called DCOL_Edit.exe. This program however, does no run stand-alone. When it is run without any arguments, it doesn't do anything. To use this tool, associate files with the extension .DCOL with this tool. This can be done by holding down Shift, then right clicking on a .DCOL file and then selecting Open With...
Double-click on a .DCOL file in Windows Explorer. The DCOL Editor should now start up and look like Fig 1.1 below.

This tool allows the eight attributes of a dynamic collision object to be edited. The actual mesh of the object cannot be edited. These properties are set up in the user properties in the 3D modelling package, and usually need not be edited further. This tool is merely for convenience, as it allows rapid prototyping of dynamic objects, as changes can be quickly made to car bodies, and other objects, and tested in the game without the need to re-export the whole scene in the 3D package. Once you are happy with the physics properties of an object, copy these properties into the original model userdata in 3DSMax to make these changes permanent in all future exports.
1.0the object will bounce back to the height that it was dropped from. At
0.0, the object will not bounce at all and come to a stop when it hits the ground.
The cars' Center of Mass can also be altered ingame. To do this use the
incCarCenterZ command at the console.
incCarCenterX 0.1will move the center of mass to the left.
incCarCenterX -0.1will move the center of mass to the right.
incCarCenterY 0.1will move the center of mass up and will make the car roll over more and be more rocky.
incCarCenterY -0.1will move the center of mass down and will make the car more stable and solid on the road.
incCarCenterZ 0.1will move the center of mass forwards and make the car understeer.
incCarCenterZ -0.1will move the center of mass backards will make the car oversteer.
Moving the center of mass left or right is not needed unless you're making a really wacky car.
