Any!!! :-D I'd like a tutorial because I've been learning 3dSimEd and when I opened the NR2003 'make_a_cts.3do' and saw all 4 models mushed together as one model, I chickened out and went back to modding rF. :-O
I've got permission from CY-33 to use his GTL 1965 Impala (which I've already converted to rF) and have found models of other cars, quite a few, and while I'm putting them into rF for the next and improved release of the "Stock Car Legends" mod,
it would be really cool to put them into NR2003 and fill those gaps between and after the GN55, GN63 and GN69/70 mods (I've got some 71-74 models and know the community has been looking for those years for a while).
So if a tutorial exists, it would be cool to find because I have no idea how NR2003 grabs the individual models out of that one, "make_a_cts.3do" mash up.
