Networked smooth turning: how to do it properly?

I recently implemented snap turning using MovementActionSnapTurn and while I was in there I added a smooth turning option using the same function. sort of works but it’s extremely choppy. I see above that you recommended AddActorWorldRotationVR for non-networked scenarios, but what should be done in networked scenarios? I apologize if is a nooby question. I’d imagine it’s more or less the same as mouse control… but don’t know enough about either system to make an informed decision here.

Love the plugin by the way. I’m using it in my game Hailstorm VR, mainly for character movement and replication stuff. And for everything else, the code is a wonderful reference for my own.

So I tracked down the cause, Characters FRepMovement structures default to ERotatorQuantization::ByteComponents.

For smooth turning for use you’ll want to go in and set them to

ReplicatedMovement.RotationQuantizationLevel = ERotatorQuantization::ShortComponents;

Byte values don’t have the granularity for smooth turning like that. And it is made worse with the root offset that VR has.

Regardless you can also set it in blueprints in the character BP here:

I am hesistant to set it to the default setting for characters due to the fact that unless you are specifically doing smooth turning it shouldn’t be an issue.

Edit actually pitch and roll should almost always be zero anyway, so they won’t rep besides the bitflag. I’ll probably default it since its a one byte cost then.

Also i’ll add your game to the using list if you don’t mind
