Add Packing options to PredictionRigidbody

[AustinEast]

Im running into issues with accuracy when reconciling my Predicted Rigidbodies, and I've narrowed it down to the RigidbodyState reconciling with a packed Quaternion - after manually updating the RigidBodyState writer/reader to use unpacked quaternions my issues are resolved.

So my request would either be to add an option to set the Packing on the PredictionRigidbody/RigidbodyState, or to expose the internal PredictionRigidbody.SetReconcileData() method so that we can easily write our own writers/readers for the type (the mentioned internal method is the main blocker for this DIY approach).

Update - I looked into the rotation quaternion issue I've been seeing, and it seems like it only happens on the client when i have Create Local Reconciles active and I'm not reconciling every frame from the server - there may be inconsistencies happening between the packed rotation quaternions from the server reconcile states and what i assume are untouched rotation quaternions from the local reconcile states.

FWIW I haven't proven this theory yet, just food for thought.

I recall we talked about this. I believe a packing option makes sense.

There's some new Quaternion packing stuff I worked on that will be perfect for this; you essentially specify precision and it packs based on that. What is normally 8 bytes is ~6.2, and 12 bytes ~ 6.7. I'll try to get this in the 4.6.0 release.

The new packing is live but not in PredictedRigidbody. I'd like to have you test if you can DM me please.
