Well, quite :p I want the surface of the wormhole to look like one single continous surface without holes and too a too significant striking structure that would look "rough".. Well, It's supposed to look like a water surface or like the effect I created with my last nurbs-surface I used (see finished work section for my finished Stargate stills), but should still be able to "build up" like you see it in the TV-series. The surface starts to build up from the centre until the whole circle is closed with one surface... The outblast should look like water being pushed down from a turbine or jet-engine when you look at it from underneath the water-surface (that's how the original effect was created I think).. All that should happen with as few particles as possible so that I could get a reasonable render-time on my quite slow machine Any help / proposal is highly appreciated! Best Regards Markuz
