Resolved Unkillable particle strip quad

Edit:

Resolved:

Solution:

1. In VFX Graph 12.x, this bug no longer exists.

2. In VFX Graph 10.5.1, use this workaround: Set the lifetime of the particle in the strip to anything to make the particle strip quad honor the

alive == false

condition, and then disable

Age Particles

in the

Update Particle Strip

's inspector to make the particle in the strip immortal until the user-defined condition is met.

Original post:

I set

alive = false

on an otherwise immortal particle strip but the quad remains (magenta below):



The blue square is a particle head, which spawns the particle strip over time.

Here is the graph:



The particle quad (blue) honors the

alive == false

condition and disappears. The particle strip quad (magenta) does not honor the

alive == false

condition and does not disappear.

The docs say that killing immortal particles should be possible:



Does anyone know how to kill particle strip quads in this case?

 

A workaround:

Setting lifetime to anything made the particle strip quad honor the

alive == false

condition. I set lifetime to one hour which is effectively immortal:



This to me implies that there is a bug: Particle strip quads do not honor

alive == false

if the particle in the strip does not have a lifetime.

 

Hi Vlad,

Sorry, I forgot to mention that I'm using 10.5.1 on 2020.3.14f1. That's great to hear that it works in 12.x.

In this version there is no Reap Particles option without lifetime:



With lifetime:



Since I'm using an old version I'm content with the workaround of setting lifetime to anything and then disabling

Age Particles

.
