- **The rig must bake on the SAME entity that holds the gameplay components the drive job reads** — `Animator` + `RigDefinitionAuthoring` on the **player root** (not a child), flatten skeleton + SMRs under it, else the drive query matches nothing.
- **CPU engine skins via Entities-Graphics GPU deformation → needs a deformation-aware material** (`AnimatedLitShader`, multi-target ShaderGraph + `UniversalTarget`; Synty atlas → `_BaseColorMap`). Stock URP/Lit renders **unskinned static** + a `"does not support skinning"` warning (NOT magenta — that's a reused HDRP sample `.mat`).
- **The 3 deformation ShaderGraphs (incl. `AnimatedLitShader`) live in `_Project/Shaders/`** — GUID-preserved `MoveAsset` out of the Rukhanka "Animation Samples" tree (then deleted; importing those samples drags in 26 subscenes + world-running sample systems + a TMP conflict). Detail → gotchas archive 07-04b.
- **First Rukhanka bake is ~60 s, main-thread-synchronous** (editor freezes — not a hang; blob cached after → fast re-plays).
- **First Rukhanka bake is ~60 s, main-thread-synchronous** (editor freezes — not a hang; cached after).
- **The server runs Rukhanka unless you strip it** — its **deformation** systems are `[WorldSystemFilter(Default)]` (⊇ ServerSimulation). **`ServerStripAnimationSystem`** (server-only one-shot) disables every `Rukhanka.Runtime` system on the server (group-disable cascades; matched by assembly name → no type ref). *Only Play-validation caught this.*
- **Build the controller via the `AnimatorController` API** (`manage_animation` drops enum/Vector blend-tree fields). **Skeleton-root = walk up from a bone to the soldier's direct child**, NOT `SkinnedMeshRenderer.rootBone` (the *bounds* root — head SMR's is `Spine_03` → destroys the lower skeleton).
- **The rig pipeline is HUMANOID** (muscle clips retarget onto player + monster rigs; the old "Generic" note was WRONG). **Blender clips:** per-action FBX (Key All Bones + Force Start/End + FBX Units Scale); import `CreateFromThisModel` (**CopyFromOther FAILS on Blender's extra `Armature` node**); bake root motion into pose. Optimize Game Objects **OFF**; root motion **OFF** (CC owns the transform).
- **The rig pipeline is HUMANOID** (muscle clips retarget onto player + monster rigs; the old "Generic" note was WRONG). **Blender clips:** per-action FBX (Key All Bones + Force Start/End + FBX Units Scale; **5.1: +NLA-strips OFF or ZERO takes bake, silently**); import `CreateFromThisModel` (**CopyFromOther FAILS on Blender's extra `Armature` node**); bake root motion into pose. Optimize Game Objects **OFF**; root motion **OFF** (CC owns the transform).
- **★ Skinned ATTACHMENTS onto an existing rig (07-16 suit-kit recipe):** Blender rigid-skin (vgroup w=1 + armature modifier; **UNHIDE the armature before selection-export or the FBX is silently skinless**) → `PlayerRigTools.GraftSmr` REBASES on rebind (verts→rest-world; bindposes = inverse of **rigid scale-stripped** rest matrices — a Blender roundtrip imports cm bones/0.01 armature, raw bindpose reuse explodes ×100; **`RecalculateTangents()` or Rukhanka/BRG registration fails and the whole rig vanishes**). Hand-written deformation shaders: DOTS-instanced `_DeformedMeshIndex` block **BEFORE** the `ComputeDeformedVertex.hlsl` include + the property ALSO in the Properties block (the baker validates `HasProperty`). [[DR-052_SoD_Facing_Underwater_Feel]].
- **ENEMIES reuse the player pipeline** — a Husk = ownerless interpolated ghost = a remote player, so `EnemyAnimationDriveSystem` mirrors the REMOTE path (`LocalTransform` delta velocity + prevPos cache; `IsAttacking = AttackWindup != 0`). **Drop `[RequireMatchingQueriesForUpdate]`** so the prune runs every frame (else a cache entry leaks per kill). Build enemy prefabs via **`EnemyRigTools`**, GUID-preserving (`DeleteAsset+CopyAsset` orphans subscene refs); `WaveSystem` uses `baked.WithPosition` (not `FromPosition` → Scale reset).
