====================== NAME ====================== Megatexture Technology Demo ====================== DESCRIPTION ====================== ====================== COMPARISONS TO QUAKE WARS ====================== * The scale of the terrain is off. * The 32768x32768 Megatexture in Quake Wars has 64 times the texture detail you have in this demo. * What would be a 5.7GB Megatexture in D3/Q4/Prey takes only ~500MB in Quake Wars. Or in other words: The 4096x4096 Megatexture in this mod would have been 7MB and not 87MB. ====================== INSTALL & RUN ====================== You need Doom 3/Quake 4/Prey. 1. unpack into the game folder. 2. run one of these found in the unpacked 'megatexture' folder: - d3_megatexture.bat - q4_megatexture.bat - prey_megatexture.bat ====================== LEGAL ====================== * May be distributed as you wish as long as long as the zip stays unmodified. * Notify me if you'd like to use the mod in your mod. * Give credit if you use any parts of this mod in your mod. ====================== CREDITS ====================== Arne Olav Hallingstad (arneolav at hotmail.com) Thanks to: * Hazel Whorley for the skybox * id Software
