How can I achieve an echo/afterimage/ghosting effect?

So, there is this effect where an object, lets say a sword, for instance, moves, and after it follow delayed ‘ghost’ images of the sword, that start and stop moving after the actual sword starts and stops moving. You see this effect in games, anime, even the matrix (think when they are moving really fast, or dodging bullets) though I can’t find out the ‘official’ term for this for the life of me, I was wondering how I might achieve this in UE4. A good example of what I want is the 8th image down on this page (the one with the golden afterimage sword): http://www.cgjoy.com/forum.php?mod=viewthread&tid=16379

Just in case you’re still looking for this, the technical term is a “ribbon trail”, and Unreal has ribbon emitters as a built in part of the particle system.

Hey Knobbynobbes -

Hoeloe is correct the effect you are looking for is called a Ribbon or in the case of attaching to a Skeletal Mesh an AnimTrail. Here is the basic emitter setup for an effect like you are looking for, A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums8-_Creating_a_Ribbon_Emitter

Also I recently helped someone attach a ribbon to a weapon here, My ribbon emitter not shows up on movable weapon - FX - Unreal Engine Forums

Good Luck -
