   Blending and OpenGL 3.0
  Hello.Is glEnable(GL_BLEND) acceptable in OpenGL 3.0 (as in not deprecated)? Or should I do the blending myself, by comparing the FBO depths and mixing the colour values myself?   
  You can't do blending yourself. Blending-modes are here to stay, not deprecated.   ;  Thanks. I got kinda misleaded by my friend, who claims that GL blending is fixed-function, and modern engines should blend between FBOs or something.Thanks for claryfing that.
