VR Expansion Plugin

[SlimeQ]

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

I actually already had rotation quantization set to short. It’s possible is just a frame rate issue, but it does seem a bit choppier than the standard mouse movement. That being said, mouse movement is also pretty choppy.

Here is a video of me comparing the smooth turn to the mouse input (which is simply setting world rot on the camera): https://youtu.be/nnYizTsCfls

The “choppiness” I’m referring to is the apparent duplication of objects during turning. It is very noticeable in VR. I don’t notice nearly as much during lateral movement, though it is still present.

It’s very possible that is outside of the scope of the plugin, but I do not recall observing while driving the car in the template project. leads me to suspect it has something to do with the VR Camera or something… but I really have no idea.

EDIT: just tried Epic’s FPS template, it gets more or less the same effect when motion blur is disabled. Unfortunate
