Model Skins
 -----------
 Risen3D models use the PNG or JPG format for their skins. If however duplicate file types of the 
 skins are present then JPG will always get priority over PNG. 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.
