Model Skins
 -----------
 Risen3D models use the PNG format for their skins, when using the Quake2Modeller the skins 
 require the PCX format. A graphics program such as PSP or PhotoShop is required for conversion
 between the two.


 DMD Model Format
 ----------------

 The DMD model format is a custom data format implemented by the Doomsday Engine. 
 A DMD model is similar to a normal Quake MD2 model, but there are two key differences: 

 - Up to four Levels-of-Detail can be specified. LODs are additional triangle mesh sets. 
   Each LOD uses the same set of vertices (which is a bit of a caveat). 

 - Vertex normals are stored in a more accurate fashion, which reduces artifacts in lighting 
   and environment mapping.

 Use SkyJakes's Md2Tool for conversion between these formats.
