PhysConstraints Asset

The physconstraints asset holds physical constraint settings for dynamic models. This asset exists only in World at War, Black Ops 1 and Black Ops 2.

Source Format

The physconstraints source files are raw text files with no extension, located at "raw/physconstraints/". They use the same format as many other assets, with each setting name and value separated by a back-slash. The first setting identifies the file, and for physconstraints the identifier string is "PHYSCONSTRAINTS". For example, here is "veh_car_launch_glass_f_mp" from BO1:
