Wow! Now THAT was a post ... Honestly, I didn't understand everythink you tried to tell me but I will try to find out what you meant, that's sure! I haven't used (well, at last not intentionally?) blend-shapes at all, so I'll read the maya documentary for that purpose. But anyway, I'll be on holiday in 2 days, and I don't think I'll be able to do all that untill then, so first of all I'll render the scene without the special effect of the wormhole outburst I think... At least in case I shouldn't be able to get the paint-effects be ivisibly behind the particles ... BIG Thanks anyway, I'll try work with your thoughts when I am back from holiday, though!
