Hello all, new user here enjoying PI 3.0 on a Mac. I have noticed that when working with some emitters (library 04-12: Dots Color Slow 06 ie.) I can adjust the size and/or zoom with the first keyframe, but when I try to animate either size or zoom nothing happens. The timeline graph shows the values changing as time passes but there is no visible change to the dots. What am I missing here? Thanks for the help.
You might be able to do it by shortening the Life of the particles. When particles are born with a Zoom value of 100%, they'll stay at 100% through out their lives. If you add a keyframe at frame 50 or so with a value of 300%, then ones born after frame 50 will be zoomed to 300%, but not ones born before.
At least I think that's how it works. Someone correct me if I'm wrong.
I tried shortening the Life value but then the dots just disappear sooner. It must just be something special about these "Dot" emitters that I am not understanding. Other emitters animate just fine in size and zoom. Thanks anyway, I'll just keep experimenting.
