Particle System Components don't show after Play

Hi there. I’m using the Github version 4.17.2.

Can anyone replicate this ?

Particle system component work fine in the editor, but aren’t showing once I press Play.

Auto activate is checked, Visible is checked, Hidden in game is unchecked, Render in main pass is checked,
All detail Modes (Low, Medium, High) have been tried. I’ve used emitter from previous versions and brand new emitters created from scratch with this engine.

Stand alone particle systems work fine, BTW.

Answering my own question. :stuck_out_tongue:

Actor has to tick for particle systems to work.

If you are using C++ to create your Blueprints, make sure all virtual functions call their relevant Super:: function.
My blueprint was based on a sub-class whose parent had a BeginPlay() that didn’t call Super::BeginPlay() and that prevented it from ticking.
