+The working directory is empty, so I couldn't find your file to edit it. Here's the fix to apply wherever the material is set up.
+
+## Why every sphere is a dot
+
+`positionNode` **replaces** the vertex position after instancing has been applied. `positions.element(instanceIndex)` is the same value for every vertex of an instance, so all of a sphere's vertices land on one point. The sphere geometry is discarded.
+
+## The fix
+
+Add the per-instance offset to the mesh's own vertices, and pass the buffer to the vertex stage as an attribute:
+
+```js
+import { positionLocal } from 'three/tsl';
+
+// was: material.positionNode = positions.element(instanceIndex);
+material.positionNode = positionLocal.add(positions.toAttribute());
+```
+
+- **`positionLocal`** keeps the sphere's vertices.
+- **`.toAttribute()`** is the official way to feed an `instancedArray` into the vertex stage on `InstancedMesh`.
+
+## Things to check next to it
+
+- **Remove any `instanceMatrix` translation.** If you also set positions with `setMatrixAt`, that offset is applied too, so each sphere moves twice. Leave the matrices as identity, or use them only for scale and rotation.
+- **Scale.** If you want per-particle size, apply it before the offset, e.g. `positionLocal.mul(size).add(positions.toAttribute())`.
+- **Culling.** The `InstancedMesh` bounding sphere doesn't know where compute moved the particles. Instances can vanish at screen edges. Set `mesh.frustumCulled = false` or give it a large enough `boundingSphere`.
+- **Order.** Run `renderer.compute(update)` before `renderer.render(...)` in the same `setAnimationLoop`.
+
+## Verification
+
+I haven't run this, because there's no project or browser here. The visual result is `NOT_RUN`. To confirm, load the page in a WebGPU browser (Chrome/Edge) and in the WebGL2 fallback (`forceWebGL: true`). The spheres should show full geometry at distinct positions in both.
+
+If you share the file path or paste the material and mesh setup, I can apply the change directly.

+That was a runaway loop of the same command, and I never got its output. Rather than retry, here's the diagnosis. Both symptoms are well-known r186 behaviours, and I can't see your code from this empty temp directory.
+
+## 1. Death pops back to T-pose
+
+A `LoopOnce` action with `clampWhenFinished = false` (the default) disables itself when it finishes. With no active action left, the skeleton falls back to bind pose (your T-pose).
+
+```js
+const death = mixer.clipAction(clips.get('death'));
+death.setLoop(THREE.LoopOnce, 1);
+death.clampWhenFinished = true;   // hold the last frame instead of disabling
+death.reset().play();
+```
+
+If you crossfade into death, also make sure nothing crossfades out of it afterward. A `'finished'` handler that returns every one-shot to idle is a common cause:
+
+```js
+mixer.addEventListener('finished', (e) => {   // on the mixer; actions have no addEventListener
+  if (e.action === death) return;              // stay dead
+  if (e.action === attack) crossFade(attack, act.idle);
+});
+```
+
+If it still snaps, check whether the clip itself ends in bind pose. Scrub its last frame in a viewer, or use `npx @gltf-transform/cli inspect hero.glb` to look at its duration and channels. That would be an asset bug, not a runtime one.
+
+## 2. Feet slide when running
+
+The character moves at your gameplay speed, but the run cycle plays at its authored speed. Any mismatch looks like skating. The usual fix is to scale the clip's playback to the actual speed.
+
+**Measure the clip's authored speed once.** If the run clip carries hip translation (root motion), strip it and get the speed at the same time:
+
+```js
+function stripRootXZ(clip, hipTrack = 'Hips.position') {  // use your hip bone's track name
+  const t = clip.tracks.find((k) => k.name === hipTrack);
+  if (!t) return null;
+  const v = t.values, x0 = v[0], z0 = v[2];
+  const dx = v[v.length - 3] - x0, dz = v[v.length - 1] - z0;
+  for (let i = 0; i < v.length; i += 3) { v[i] = x0; v[i + 2] = z0; }
+  return Math.hypot(dx, dz) / clip.duration;   // m/s as authored
+}
+const runAuthoredSpeed = stripRootXZ(clips.get('run')) ?? 3.5; // in-place clip: measure by eye, tune
+```
+
+**Drive `timeScale` from real speed every frame:**
+
+```js
+const dt = Math.min(timer.getDelta(), 0.1);             // clamp: no jump after a hidden tab
+act.run.setEffectiveTimeScale(currentSpeed / runAuthoredSpeed);
+mixer.update(dt);
+```
+
+Also check these:
+- **Hip translation not stripped.** If the clip moves forward and your code also moves the character, the motion is counted twice. Strip it as above, or export the clip in place.
+- **Walk to run transitions.** Use `from.crossFadeTo(to, 0.25, true)` (warp on) and match phase so the same foot is down after the switch.
+- **Retargeted clips (e.g. Mixamo).** A different leg length changes the stride. Re-measure the authored speed on the target rig; don't reuse the source's number.
+- **Unclamped delta.** In R3F/drei, `useAnimations` passes a raw delta. Clamp it in `useFrame` yourself.
+
+## Status
+
+Both fixes are **NOT_RUN**: I haven't seen your code or model. To verify, check that:
+1. After death the body holds the final frame for several seconds.
+2. At several run speeds, a planted foot stays fixed against the ground (a grid texture helps).
+
+If you share the file that sets up the mixer and the path to the `.glb`, I'll inspect the clip names and hip track and apply the changes directly.

+The meshopt half is done: **80 MB → 30 MB** in `public/models/warehouse.meshopt.glb`. The file validates clean and the original is untouched. KTX2 is blocked because there is no `ktx` CLI on this machine.
+
+## Where it stands
+
+| Part | Now | Fix | Status |
+|---|---|---|---|
+| Geometry (Shelf: 412k tris × 24 copies ≈ 9.9M tris drawn) | was 58.4 MB | clean, conservative simplify, instancing (62 instances), meshopt | **done** |
+| Textures: 4 PNGs, 2× 4096², 2× 2048² | ~21.5 MB file, **~224 MB GPU** | KTX2: ETC1S colour, UASTC normal | **NOT_RUN** (no `ktx`) |
+| Loader compatibility | writes `EXT_meshopt_compression` | this is the variant drei's `useGLTF` reads | ok |
+
+Notes:
+- **Textures are now most of the file**, and they cost far more in GPU memory (~224 MB) than on disk. KTX2 is the bigger win there.
+- **Simplify ran at the default error of 0.0001.** It's conservative, but check the shelf silhouettes before you ship.
+- **The 9.9M triangles drawn is the real runtime problem**, separate from file size. That Shelf mesh is heavy for something repeated 24 times. I haven't cut it harder because you have no written budget yet. I'd suggest one, e.g. ≤ 1–2M scene triangles and 2048² textures.
+- **Your `<Canvas>` uses the default WebGL renderer**, so drei's KTX2 path will work. You'll need to host the Basis transcoder yourself, and the Draco decoder too, since drei defaults it to gstatic.
+
+## Next action (needs your OK)
+
+Install **KTX-Software ≥ 4.4**, which provides the `ktx` CLI. The older `toktx` is not enough. You can get it from the KTX-Software GitHub releases (macOS .pkg); I won't install system tools without your go-ahead. Once it's on PATH, I'll:
+
+1. Encode from the original PNGs using `--texture-compress ktx2` (UASTC normals, ETC1S colour). I'll resize to 2048 if you accept that budget.
+2. Copy `three/examples/jsm/libs/basis/` into `public/vendor/basis/`.
+3. Wire `useGLTF(path, true, true, loader => loader.setKTX2Loader(...))` with a KTX2Loader that has `.detectSupport(gl)`, and point it at the new file.
+4. Validate, measure, and write `warehouse.manifest.json`. The manifest needs the model's source and licence, so tell me where it came from (Blender export by whom?).
+
+If you'd rather skip installing anything, I can use WebP textures instead. That gives a smaller download, but no GPU memory saving.
