OK. I usually work from the .obj file rather than export in order to be sure that I got the model in is original position. After reading your posts I suppose that I have to use the export for this model in order to get it split up in parts. What I was confused about is if applying a morph made for a part was possible to apply to a model that not really is made of parts. The appearance of several parts with the same name is probably because Wings goes nut on the fact that group and material info in the file (at least the original .obj file) is least to say unstructured. After running the model trough my app it's sorted in a nice way with also means that I don't have that problem with the model when imported to Wings. What concerned me when working on it in my app was that Wings added thousands of vertices to the model when loaded and when I tried to weld the model in UV mapper in order to validate the function of my own weld function there was nothing to weld. So when it comes to this model I suppose I either have to handle it another way than the other models or I will have to work on an exported version instead.
