Razor,
The thing is that the meteor has to travel a great distance and the exhaust trail is pretty long before I have it begin dissipating. Unless you can suggest something, the two possibilities I can think if would be to: 1- have a really big fluid container or 2- animate a smaller container to fly along with the meteor and it's tail. To be honest, I haven't tried the "flying container" idea yet but I never considered that by moving it, I'm also moving the position of each voxel. I can understand how that could cause visual changes. :headbang:
