   Multitexturing or Alpha Blending or ?
  I''m working on a terrain engine and i''m wondering how current games are able to blend these textures.  Look at the link to the picture below to see what i''m talking about.  Like how to they texture the round and make it blend in with the grass.  Do they use 2 different textures with multi texturing and then change the alpha on one to become more transparent.or is that just a seperate texture map that has some grass and some road.any comments would be helpful thanks.http://www.angelfire.com/games5/gimpmaster/images/vengeance_080103_004.jpg 
  My guess is if the scene is static... aka no roads are added or the grass doesnt change color with seasons or what not that the texture for the scene is merely made that way in advance.If the terrain is dynamic but at load time it is possible to create a bigger texture from smaller textures and blend them at load time.Another alternative however would be blending of textures using maybe a pixel shader in order for it to be fast enough during run time.   // Full Sail Student with a passion for games// This post in no way indicates my being awake when writing it ;  Yeah i''m pretty sure its static but how did they do it with it being static.
