I once saw someone mention that it is possible to set the file paths for the meshes and textures a certain way in order to allow different races to have different body types. How does one do this? Maybe someone could link me to a tutorial?
It's an option in the race body data in the G.E.C.K. It won't affect armor meshes, though; they'll still use whatever mesh is defined for that armor item.
Just put the different body meshes somewhere in the Data/Meshes folder, then go into the G.E.C.K. and edit the races to use the new meshes. I's really that simple.
