Starfleet Command Model Editor. Sometimes referred to as M6.
You can download it here.
http://www.geocities.com/ccc004/I would like to be able to use Milkshape, but it doesn't work. I think it may have something to do with my video drivers. Unfortunately, I can't get new ones because the latest drivers screwed up my computer. I may have to upgrade from Win98.
Before I discovered SFC, I did kitbashes of X-wing series OPT files. Optech was a very efficient editor that allowed me to do so much including edit hardpoints, engine glows, and putting parts from one model onto another without losing the textures. Why hasn't anyone made something similar for SFC? Give us newbies a chance.
