Netcode tutorial should include this:

Netcode tutorial is missing these 2:

[CreateBefore(typeof(Unity.NetCode.TransformDefaultVariantSystem))]
public partial class DefaultVariantSystem : DefaultVariantSystemBase
{
protected override void RegisterDefaultVariants(Dictionary<ComponentType, Rule> defaultVariants)
{
defaultVariants.Add(typeof(LocalTransform), Rule.ForAll(typeof(DontSerializeVariant)));
defaultVariants.Add(typeof(KinematicCharacterBody),
Rule.ForAll(typeof(KinematicCharacterBody_GhostVariant)));
}
}

[GhostComponentVariation(typeof(KinematicCharacterBody))]
[GhostComponent(SendTypeOptimization = GhostSendType.OnlyPredictedClients)]
public struct KinematicCharacterBody_GhostVariant
{
[GhostField(Quantization = 1000)] public float3 RelativeVelocity;
[GhostField()] public bool IsGrounded;
}

Took me days to figure out why my jumps were jittery, these 2 lines of code from the online fps sample solved it for me

Find the Netcode tutorial in the repository and identify where the missing guidance belongs. Add the two code snippets from the issue, and consider the work complete when the tutorial includes both examples and their relevance to jump jitter is clear.
