I want to make some characters and weapons from the ground up, meaning I want to make the frames how I want them and stuff. I want to make really unusual weapons (such as guitars, light sabres, etc...) and also some unusual characters (such as small trolls and llamas amd the like). How would I go about doing this? What programs would I hafta use? Is there anywhere I can go that has like tutorials about this?
