Particle Color Parameter resets all other vector parms to 0,0,0 when changed


I have a particle object with multiple parameters. I have several that are vectors. One is color (marked as color), but when I change the color value, it resets all the other VECTOR parameters (on the particle actor in the world) to 0,0,0.

It’s quite annoying to dial in an initial velocity, acceleration, etc, then have them all reset to zero if you need to change the color.

Hi Vall,

Thank you for the report. I was able to reproduce this behavior so I’ve created JIRA UE-46672. Our developers will be investigating further but please keep in mind that we plan to roll out a new particle system in the future that may make fixing this irrelevant.
