Hi Guys,

I'm having problems with sprites that now i cant even count how many I have...
but I need a solution for this first problem... how do I tell mantra .... how many overlapping sprites to consider?
is there a sort of "ray depth"?... I have a sphere which emit static particles... and such particles are shaded with a
VOP shader which makes a gradient opacity...

when sprites overlap (quite always in my case) I've got a square.. with black area where it should be transparent...
Alpha in mplay is what I'd expect.. its ok... but color... nope.

thanks for any help....

p.s. I'm trying to make a smoke effect with sprites...
