This plugin is provided for free as a way to easily spawn GhostTrail2d within PaperZd anim sequences using an extended PaperZd notify.
Compiled releases for various unreal engine versions can be found here along with the source code should you wish to use it yourself.
This notify is provided to allow easy use of spawning ghost trail 2ds from within animation sequences. It takes care of a lot of the setup including passing in the sprite and spawn transform from the character flipbook. It allows you to select a Ghost Trail 2d class so can be used with any Ghost Trail 2d type, however if any additional parameters are used it will only be able to pass in the defaults for that class.
The parameters of the notify should correlate 1:1 with the Ghost Trail 2d class whilst also allowing you to offset the the spawn transform relative to the character via the "Offset" transform.
This notify behaves as per the default Ghost Trail Zd Notify, however is specifically for classes that derive from the Ghost Trail 2d Material Parameters class and as such provides the option to change the material parameter used.
