 Physics materials are a way to group common behavior among certain objects, but contrarily to rendered materials, you can also *not* assign a physics material to an object and set each of those four parameters individually.

 ## Conversion from Visual Pinball

 When importing a `.vpx` file, VPE converts the "visual part" of Visual Pinball materials into materials for the current render pipeline. It does that by creating a new material for every material/texture combination in Visual Pinball. The materials are then written to the `Materials` asset folder of the imported table where they can be easily edited and referenced. Since Visual Pinball uses different shaders than Unity, the results of the conversion are approximations and should be heavily tweaked. 
 
-Since VPE uses the same physics engine as Visual Pinball, the physical values of the materials don't need to be converted, they are copied 1:1 into a new physics material and saved in the asset folder.
