   Controlling model transparency [SOLVED]
  I was wondering if it is possible to control textured model transparency accordingly:void drawStuff() {  setTransparency(alpha); // set transparency for model.  glDrawElements(...);    // draw model with transparency}/* ... */void setTransparency(float alpha) {  alpha=clamp(alpha,0,1);  /*   *  ?   */}I'm looking for a solution which is something like this. Is this possible?As I was researching this I noticed glTexEnv was mentioned few times, but I don't quite get it :|EDIT: Adding following code solved the case: glEnable(GL_COLOR_MATERIAL);glEnable(GL_BLEND);glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);glColor4f(1,1,1,alpha);my problem was that I had the "glEnable(GL_COLOR_MATERIAL);" missing. I think this is because I had lighting enabled.[Edited by - rxa on February 23, 2010 11:20:21 PM]
