I have tried importing the model on my end, it imports into the program for me, although I have noticed that the model is very high poly and some of the meshes included exceed the vertex limit [17,433] for SMD files which are generated to compile the model for the game, so the model will probably not compile correctly. Although I may need to ask if you are talking about just importing the model into the editor or compiling it for the game, since it does import into the editor for me
In addition for the vertex limit, I may have to use DMX instead of the SMD file format which will require me to rewrite some of the code, although I do want to rewrite some portions of the code later on
