[Particles] Invalid AABB / InFinite errors in 5.3.1



When (some) particle systems are activated the Debug.Log spews Invalid AABB result / InFinite(d) errors. It seems to be only with particle systems manipulating meshes. Only started happening in 5.3.1

    In 2018.3.0f2, fixed by disabling "Limit Velocity over Lifetime" on the particle system causing the issue.

    If you still have the issue, try disabling "Velocity over Lifetime" too.

    I'm running version 2018.2.11f1 and I'm getting the same error too too. It would seem if I disable "Velocity over Lifetime" that the problem goes away. It's really important to me to have "Velocity over Time" enabled - it provides the exact movement I'm looking for.

    Scratch that previous post, it seems like setting speed modifier to 0 for velocity over lifetime with curve messes with the system.

    Hey guys, so I've been scratching my head over this error as well. None of my scripts were the cause, however. I had my size over lifetime module set to start at the middle of the lifetime. I assume up until that point was reached, the size was NaN or something of that sort. Upon disabling size over lifetime, this got fixed.

    Sorry, forgot the version.
    In 2017.3 to reproduce:
    Create a new particle system, set Start Lifetime to Infinity (you might want to also set rate to 0 and add a one-time burst so you don't fill up with particles).
    Starting the particle system (in editor or by hitting play) will show the errors. Changing lifetime to a number stops the errors.

    I've set a new particle system's Start lifetime to Infinity and got these errors.
    Changing it to a number stops the errors.
    Both in editor (start simulating gives the errors, stopping stops them) and in game (via play).
