Hi everyone, I'm developing a 2d game using MDX for graphics. I'm currently trying to use point sprites for some particle effects, but I'm having problems with the positioning. It basicly seems like they ignore world/view/projection, or rather that they use their own. They act as if they were drawn in screen-space, but with the center of the screen as 0,0. I use ortho projection, can this cause problems? I set the PointSpriteEnable, PointScaleEnable, PointSize, PointSizeMax, PointScaleA/B/C renderstates. Can bad values for these cause problems? Does anyone have any ideas? [Edit] Never mind, it's just me being stupid. I forgot to reset the world matrix after rendering a quad at the center of the screen.
