Don't know what went amiss before. I have the Flash plug-in. But the new URL you sent worked fine. That is bloody dramatic!

But...if that's a Flash animation, [unless I'm mistaken] I can't get the same effect in a Carrara animation, can I? In any event, I'll certainly see what the 'fire' effect can do. Thanks again.

I agree with nomuse: the particle preview window is not a good indicator of what you're going to get.
