Do you have blueprint graphs of what you’re trying to do? I believe the old plugin has correct directional vectors so it may depend on how you’re trying to achieve it.
I’d recommend checking out the Blocks demo on leap motion’s website. It’s a good test for checking out the sensor quality in vr.

While the demo is built in unity, you’ll have similar tracking quality in the new unreal plugin.
