Three Animations On Top Of Each Other

AnimationBlender

A layered system with weighted blending, so recoil, landing impact and movement can all be true at once instead of fighting each other:

• ▸Procedural recoil layer.
• ▸Procedural landing layer.
• ▸Procedural movement layer.
• ▸A standardized Humanoid Rig bone mapping for player models.
• ▸FBX and glTF animation import tools and scripts.

Wall Jumping Stopped Shaking

The instability was fixed "by isolating physics state" — the wall grab was holding physics and animation in the same place, and one of them was winning.

Momentum preservation also landed properly: charging now correctly captures incoming velocity for a realistic reflection, and the cvar compliance work made sv_walljump_minheight and sv_walljump_chargetime actually mean what they say, with strict ground checks so you cannot wall jump off a kerb.

Three New Guides

• ▸`physics-system.md` — CollisionManager, the backend abstraction

(q3 / brush / clipbrush / babylon), the Trace API, TraceResult, PatchTessellator, ContentFlags and collision masks.

• ▸`movement-system.md` — a full cvar reference of ~50 movement variables,

crouchslide, wall jump, ledge grab, ground detection and slope handling.

• ▸`viewport-effects.md` — ViewportEffectsManager and the four built-in effects:

WalkBob, LandingImpact, SpeedFOV, StrafeLean.

• ▸`weapon-system.md` — WeaponViewManager, ProjectileManager, bob and ADS

cvars, handedness.

The ~50-variable reference is the tell. By this point there are enough tuning knobs that a player-facing document is a feature, not a nicety.

Known Issues: none stated.
