   texture blending problem [solved]
  hi,i am using GL_RGBA textures to create a transparency effect.now my problem is best explained by looking at the following picture.you can see that the above course-texture blends well over the background-texture, but not over the quit-texture below. it just seems to cut it away. what could be causing this?thanks!   
  enable glAlphaTest  and call glAlphaFunc(GL_GREATER,0.8); or something. play with this value.   ;  thank you!that helped!
