@FireblitzSpain I recently submitted a new version of the plugin that should fix the stuttering issues. It should show up on the marketplace soon.
I’m a little stumped on the crouching issue though. It seems to me that crouching is handled via replicating the bIsCrouched boolean, so it should work exactly the same regardless of if you are using Smooth Sync or Replicate Movement, since it doesn’t seem to depend on Replicate Movement at all. As long as you are setting that boolean on the server it should be replicated and the character should crouch. And it does in fact seem like crouching is happening in that video (that’s why the character sort of twitches through the floor for a second), but for some reason the crouch animation isn’t playing. I suspect this has something to do with how you are triggering the crouch animation. None of the templates seem to have the crouch action / animation hooked up though so I’m not totally sure what the “right” way to do that is. It seems like you’re saying the crouch animation does play for you when you use Replicate Movement though. Is this the case? It would really help if you could either send me your project or walk me through how you’ve implemented crouching so that it works and plays the animation using Replicate Movement.
