Hi,
please give a look at your x export file. When I import it in Med only one
texture is visible, and it is not fit. So if I want get a mdl file made with
3d world... I export it as map. I open it with Ultimate Unrwap, I save in Msd3.
With Milkshape(1.7.6) I export in X, and after it match in MED. Very strange.
There is another problem to import a x file from 3d world : e.g. a model with
5 skins, in Med I get 288 skins, a very big size file.
Maybe a different version of X ?
