#interpolation

A per-frame visual-smoothing offset computed from raw fixed-tick state double-smooths against the engine's built-in FixedUpdateInterpolation, producing a 50 Hz sawtooth that reads as model flicker on stepped terrain — delete the manual smoother or compute against interpolated state.

An overhead name tag or health bar anchored to a per-player gameplay field freezes over a remote player's spawn position while their model walks away — anchor off the networked transform instead.
