Question by sg_sckirtland · Dec 12, 2016 at 08:42 PM · particlesparticle animation

Unity 5.5 - Particle Burst - Size Over Lifetime

hey folks I am experiencing something strange with a particle burst animation in Unity 5.5. I have never seen this happen before... But I am trying to use one particle in a burst. I want it to grow over its entire lifetime. Should be very simple.

I've changed the curve in Size Over Lifetime to match what I would like to see. However, the animation actually happens within a fraction of the lifetime.

Is there a new checkbox I have left unchecked? This is strange. I increased the Start Lifetime to 5 to see if I could even see the animation, and it happens within 1 second in the simulation. Strangely, any other "over lifetime" animation works as expected.

Anyone else seeing this issue? Thanks in advance for your help.

Here's a copy of my emitter:

Your question is unclear to me. Do you mean the particle "dies after 1 second" or "stops growing size after 1 second but dies after 5 seconds"? If it's the latter, it's probably because of the default "max particle size" of 0.5 in the renderer module.
