Hello; Im trying to get a good particle system for a rally game (not ligting/shading on particles), where the tires have to emit a lot of dust/sand...but im having problems to configure it...sometimes i get very bright particles (when using GL_ONE, since its additive) and sometimes bleck-bordered ones....how do i mix a blend mode + RGBA texture + RGBA color(from terrain color) to get a nice result? Thanks!

I would think your best bet is just to use a cloud puff looking texture or two and just set the alpha value to around 10-25% then just layer the suckers up. Alpha blending should be all you really need. Minor values will let the backgound show through , yet be able to get dense once enough layers are added.

I guess that leaves some color matching issues for you most likly(if you have more than one color of dirt.) Best bet there I guess is to make the puff grey and color it depending on the surface you are on. How difficult that would be probably depends on your engine you got there.
