I have a point sprite that I want to be affected by light, but I also want it to be affected by diffuse color. Do I have to use 2 texture stages for this or is it even possible? i.e. 1) No light, no point sprite. 2) Full Light: A) Black diffuse color, then no point sprite visible B) White diffuse color, full sprite visible C) Pure Green diffuse color, only green sprite visible. I want my scene to be able to be dark, but I want the point sprites to be dark during this time as well. The other thing is, with a light on the point sprite, which has no normals, nothing is reflected. What are my options there? Can I make point sprites with normals? Seems kind of strange since they always face the view...but I don''t even know if you are allowed to put that into the structure. Thanks, Chris

I determine which way is supported, point sprites, shader, or lastly quads. Then I use that method for all particles.

I''m trying to stay away from quads because of the performance issues, and the particle system will be mostly used for small, large amounts of particles. My shader is a good in-between to the quads and the point sprites, but the point sprites are by far the fastest and probably more supported by vid cards.

I figured it out with the shader and quads, but the point sprites don''t do what I''d expect. I guess next time I work on it, I''m going to try to put normals in the point sprite structure and see what happens! I''ll post if it works. Feel free to post if it won''t, so I don''t waste my time. And all other suggestions are appreciated.

Thanks!
