Hi, I''m using GL_POINTS for my ParticleEngine (for now); When I draw them with glBlendFunc (GL_SRC_ALPHA, GL_ONE) It seems like the points are semi transparent textures that hide other points behind them. Look at this Screenshot; I tried some BlendFunc''s but I have''nt found any useful. Note (GL_POINT_SMOOTH is on); thanks; StryX;

Post more code.

Have you set depth buffer to read-only? (glDepthMask (GL_FALSE))
