Particular - stop birth but still scale

I'm sorry, I don't know how to word this best for the search... what I tried brought nothing relevant up..

I need to have a cloud of floating particles... that have a longer life but that don't have an active birth any longer... they also need to increase in size over their life.

This all works fine if birth rate stays a positive number... if I keyframe birth rate from say 5 to 0 to stop new particles from being born, I can no longer animate the size or size over life. Any insight into what I'm doing wrong?

Thanks!

I think you just need to adjust the Size Over Life graph. Once a particle is born, you can't animate its size in the Size property itself.. but ALL particles are affected by the Size Over Life graph.


Maybe start the graph in the middle and then have it move upward?

Or maybe I am not understanding your question.
