Spawn Particle System on Anim State crashes UE4

Hi guys, i’m was testing the use of Anim Notifies States by creating a custom one. On the Begin Event I created a Particle System At Location.

The problem comes when i try to use this AnimState on an animation of the AnimBP when it comes to the point of displaying the preview of the Animation, UE4 crashes 100% of the times.

Is this a bug or am I doing something incredibly stupid?

Cheers

Hey HeavyBullets,

I’m getting a crash when I open the Animation Sequence that uses this state after hooking up the variables (it didn’t crash without the variables hooked up). However, I can’t get it to crash in game. Can you either migrate your content to a blank project or set one up with the mannequin? You can send a download link in a PM on the forums.

Hi there, the issue appears to be on the AnimBP, i guess it has something to do with the mehs not having an owner or the owner not having a world. I re-coded this for c++ because i needed to be able to store properties on the AnimState (which by the way, the blueprint should be able to do).

I’m gonna check the old implementation of the state on the blueprint code.
Greetings

I’m marking this as resolved for tracking purposes. If you find anything new, let me know.

i mean sure, if it’s normal for the engine to crash like that i have no problem. It should at least show a warning or catch the exception graciously. not crash like that with no prior warning

I need to get the information you seemed to indicate that you were checking for in the older implementation. I need info like a callstack and logs to check in our system for the crash.

What I had indicated in my first comment is that I cannot reproduce the crash that you are seeing. The crash I was seeing has only ever occurred for me (according to our crash report system) and was logged accordingly.

Marking it as resolved when waiting for additional info is standard procedure for our tracking system.
