Copy Motion node questions

I’ve implemented the Copy Motion node mentioned in the GDC animation presentations about Fortnite motion matching, but I’m having trouble figuring out how to set up the inputs and outputs.

This guide was enough to get the node into the game and get some basics set up, but I’m not exactly sure what the node itself is outputting, or even if I’ve set up the trajectory input data correctly: https://eoshelp.epicgames.com/s/article/Using-Copy-Motion-node-for-layering-with-Motion-Matching

Is there anybody familiar with this node setup who can expand on this article with a couple more details on how to configure it?

How did you manage to get the node into the game? I’m trying but it’s just gives me a tons of errors.

In the end I managed to add it to a plugin.
