I am trying to use the particle system to make one particle grow over its lifetime, but I can’t seem to get the lifetime curve to actually be realized. I can change the size of the particle by changing the min particle size (under renderer), but even with the min of 0 and a max of 10, the size curve I have between 0.1 and 1 does not get rendered. (In fact, with a min of 0, nothing gets rendered at all.) Color over lifetime appears to be working properly. Any help would be appreciated.
In the renderer, set the min size to 0, and the max size to 1, then adjust the Start Size in the particle system options. the size over time should work now.
