Hi, at last I solved the billboarding problem about the particles. I've changed some settings into the ssgSimpleState object, used to add the texture to particles, and the size of the bounding sphere. Now, even with the data stored into the GL_MODELVIEW matrix the objects are always visible.
So, I don't need to get the view position and orientation data to correctly rotate the objects. Thanks, Luca ____________________________________________________________ Navighi a 2 MEGA e i primi 3 mesi sono GRATIS.
