Why do my particles stop growing halfway through?

Hello! I set the size grow parameter of my particle animator to 1. The particles do grow, but they stop halfway through their lifetime and complete their animation at a fixed size.

Any idea? Thanks!

Increase the max particle size in the particle renderer.

The max particle parameter seems to cap a growing particle in screen-space when the particle is set to Billboard. It does not cap the growing of a particle set to Billboard Horizontal
