Ok, what you want to do is make your model and then export it as an OBJ file ( i think) then go to
MY_DOCUMENTS
and there should be a folder called
MY_CB_MODELS
in there you will find your model to then wich you can import into weapon creator then into fpsc
Oh Bro this will also help you out if you need some tips for cb model pro. Here are some video tuts on The Basics and on About CB made by my Buddy Danial Wright

i hope this helps
