 id Software's Megatexture tech uses [[Decal]]s and multitexturing to create their terrain textures, which are then baked down in a preprocessing step into a huge texture sheet, that's dynamically loaded as you play the game. So it's not really multitexturing in the end, blending in real-time, instead it's a single colormap baked from a multitextured source. The Splash Damage wiki has an article about [http://wiki.splashdamage.com/index.php/A_Simple_First_Megatexture generating Megatextures for ETQW].
