But since i'm beginner to that all, i can't really help to maintain the development and fix the bugs of this plugin. I wish i know the data structure of dff/txd/ifp/ipl gta files, good with python language, and experienced with blender. Some bug existed and caused some files unable to be imported/exported. The add-on is not perfect, it's still in beta version and probably already abandoned by the developer. I want to share this plugin/addon i found for Blender, it can be used to modify model, texture, animation, map file of GTA (III ?/VC ?/SA), good alternative for those who can't afford ZModeler or AutoDesk 3D Studio Max.
