want to convert .cmp to .mdl

I want to convert some models from Freelancer, like station parts and such. I have been doing some modelling for Freelancer, but I dont have the right tools for making .cmp files, which are the physical models for the game. So I thought that exporting them to a different format might not require the same deal as making them for the game. I wanted to use some model that I have seen in some mods, but I can’t find any explinations that are clear or a converter to so do. I know that I’ll need the .tga files for the textures. Anyone got a idea how to export .cmp files?
