Nice, that worked! Thanks for the tip!
Hey, sorry for forgetting to check back in here. I followed your advice and it worked! In the end I cranked the end point of the Size variable up to 10-15 sec before I could see an appreciable difference, but long story short this is exactly the effect I was hoping for. Thanks for the help! This could save me a lot of particle effects in my game project, so might soon be time to get the full version.
