Hi Guys,
Well Obio, agreed that's true if you want to modify it in some meaningful way, but actually you can do a lot with scasm and a hex editor. You can turn a VC off, so it does not show, relatively easily. You can also rip one VC out of an ac and put it in another, but that's scasming for the experts. Now, Mav, if you're looking in? He's one such person who's done it, but certainly not easy.
What it comes down to, easy if you have the source mdl. Then difficult and extremely time consuming with a lot of scasm and hex reading/understanding to do the other. The VC has a set of hex codes (as all parts do) which relate to it's drawing and display, so it's matter of understanding what and where they are, and where they fit into the scasm code of the model. A lot of trial and error involved.
Caleb Flerk's 'bible' a 'Guide to Speshul Efeks' is the place to start, if you're serious on doing some.
Cheers
Shessi
