Question: I'm thinking about one or two projects I want do try to mod in the UFO series. Which game is more moddable : Afterlight or Aftershock with regard to : 1- Can ingame models changed with an 3d modeling program or just with a hex editor? 2- Which game has the thighter engine restrictions (what can I do?) 3- Overall difficulty of changing things (like how much coding and such) Anyone can answer this, anyone mdded both games? Thanks to : Slaughter for first answer. Ill edit first post accordingly every time. 4- How can the firing effects of as/af be edited? I saw a few custom effects in the mods ive played, i think its the easier part for me to start. Is everything text based, or can they be edited by creating new for example dds. files?
