Character Movement parameter effects

Units follow Unreal's centimeter-based world unless the project changes conventions.

Parameter	Primary effect	Increasing it does	Important coupling
MaxWalkSpeed (cm/s)	Maximum ground speed; also maximum lateral falling speed	Raises travel/top air-lateral cap	Acceleration, braking, animation stride
MaxAcceleration (cm/s²)	Rate velocity can change from input	Reaches desired velocity/direction faster	Ground friction, analog magnitude
BrakingDecelerationWalking (cm/s²)	Constant deceleration with no acceleration	Shortens coast/stopping time	Braking friction/factor
GroundFriction	Ground movement control/friction	Increases directional grip and braking when shared braking friction is used	bUseSeparateBrakingFriction
bUseSeparateBrakingFriction	Selects dedicated braking friction	Separates turning grip from no-input stopping drag	BrakingFriction, factor
BrakingFriction	Drag coefficient while braking	Shortens coast when separate braking friction is active	BrakingFrictionFactor
RotationRate (deg/s)	Rotation change rate	Turns facing faster	Only used by controller-desired or orient-to-movement modes
AirControl	Lateral control during falling	Permits stronger steering in air	Boost multiplier/threshold, falling friction
FallingLateralFriction	Drag on lateral falling motion	Removes lateral velocity faster in air	Braking deceleration falling
JumpZVelocity (cm/s)	Initial upward jump velocity	Raises jump and airtime for fixed gravity	Gravity scale, jump hold
GravityScale	Multiplier on character gravity	Increases downward acceleration and shortens airtime	Jump Z velocity
MaxStepHeight (cm)	Maximum step-up height	Traverses taller ledges without jumping	Capsule, floor angle, geometry
WalkableFloorAngle (0–90°)	Maximum walkable slope	Accepts steeper surfaces as floor	Floor normals, slide design
PerchRadiusThreshold (cm)	Rejects edge contacts near capsule rim	Requires more capsule support to perch	Ledge behavior, capsule radius
MaxWalkSpeedCrouched (cm/s)	Crouched top speed	Speeds crouched travel	Crouched capsule and animation
MinAnalogWalkSpeed (cm/s)	Speed at minimum analog tilt	Raises low-stick movement floor	Dead zone and response curve

Tuning method

1. Tune a clean flat test lane without animation-driven motion.
2. Measure time to 90% speed and stopping distance, not just max speed.
3. Tune direction reversal separately from release-to-stop.
4. Add rotation ownership and rate.
5. Test stick magnitudes, keyboard digital input, low and high frame rates.
6. Add animation and correct stride/lean presentation after trajectory is approved.

Do not publish universal numeric presets. Desired scale, camera, genre, capsule, animation, and network conditions change what feels correct.
