csp sprites?

I am using the csp particle system (thanks JFK) in my game.
I just have a strange bug. The particles are only showing up if there is an object behind it, and then the particles are clipped to the shape of the object. It would be a neat efect if it was intentional, but it's not.
I think it has to do with the drawing order but I can't just use entity order becouse then the exposions will apear in front of objects even if it has move behind it.
Any ideas?

Sounds like it is one of these problems:

alpha z-order problems, use additional or multiplying blending modes instead.

Graphics-Card Driver problem - try to get the latest update for you Cards drivers. (Seen disappearing alphaed meshes problems on Ati Cards)

Yep that was it. I just comented out the alpha camands and it workes perfect. Thanks again.

Well I got it working normal again, alpha and all. It was my skysphere. It just needed to be drawn last. By the way Your system Rocks!

Thanks. Well, a single surface system would be faster, but as long as you don't use more than a few hundred Sprites at a time, it doesn't matter that much.

Oh yes,and there was a bug inside, I fixed it here, but then forgot what it was :). I think it had something to do with the random-rotation parameter.
