Hi Kelley, As a rule, I try to avoid changing the size of the actual generator over time. I get much better results by adjusting emit speed area and generation, air resistance and gravity. That way the particles themselves stay the same size. As for the hot point, if you have it locked to the center of the object, as the object gets bigger it will reposition itself. Also explore increasing the emit area using a second generator timed to go off slightly after the first one. This will provide a good second "push" to the explosion. I'm actually using a large emit area to create insects flying over fields right now - just a different use. :) You are correct in thinking you can drag emitters from the browser into other documents - same explosion different documents! Give the time it takes to set some of these up, it's nice to be able to reuse them.
