The two reference frames in `/home/ubuntu/task/input/reference-images/` show the intended swept-back brown hairstyle and its subtle motion between frames 1 and 30.\n\nPreserve the supplied `head` mesh topology, transforms, skin material, active camera, lights, and world. You may add collision physics to `head`, but do not remodel or replace it.\n\n## Scalp and groom\n\n- Create a separate mesh object named exactly `scalp`, fitted closely and coincidently to the upper head surface.\n- Keep hair roots off the face, forehead, ears, and neck. The scalp must not visibly poke through the head.\n- Use Blender 4.5 legacy particle hair on `scalp`.\n- Groom a natural swept-back silhouette with readable clumps and curl. Avoid a uniformly wet, helmet-like, or plug-like result and avoid intersections with the head.\n- Set the viewport child percentage to 10%. This refers to the particle system's viewport children, not hiding 90% of the parent hairs; retain the full rendered child density.\n- Use a brown Principled Hair BSDF material.\n\n## Dynamics\n\nEnable hair dynamics with gravity and make `head` a collision object. Frames 1 and 30 must show subtle but real simulated movement without explosions, tunneling, or tearing. Evaluate the simulation sequentially from frame 1 before rendering frame 30.\n\nKeep the existing Cycles camera, lighting, 640 × 480 resolution, and bounded sample setting. Each frame must remain below five minutes on the task machine.\n\n## Outputs\n\nCreate exactly these deliverables:\n\n- `/home/ubuntu/task/output/submission/result.blend` — the editable scene with scalp, hair system, dynamics, and collision intact;\n- `/home/ubuntu/task/output/submission/hair-frame-001.png` — frame 1 rendered from `result.blend`;\n- `/home/ubuntu/task/output/submission/hair-frame-030.png` — frame 30 rendered from `result.blend`.\n\nReopen the saved blend and verify that the particle system, material, collision settings, and both frames work without external files.\n"},{"step_id":2,"timestamp":"2026-09-04T16:55:50.413148+00:00","source":"agent","model_name":"claude-opus-5","message":"Analysis: I'll start by inspecting the environment and the input file.","tool_calls":[{"tool_call_id":"call_0_1","function_name":"bash_command","arguments":{"command":"ls -la /home/ubuntu/task/input /home/ubuntu/task/input/reference-images /home/ubuntu/task/output 2>&1; which blender; nproc; free -g | head -3","timeout_sec":60}}],"observation":{"results":[{"content":"{\"exit_code\":0,\"stdout\":\"/home/ubuntu/task/input:\\ntotal 1032\\ndrwxr-xr-x 1 ubuntu ubuntu 69 Sep 4 16:55 .\\ndrwxr-xr-x 1 ubuntu ubuntu 27 Aug 7 05:45 ..\\ndrwxr-xr-x 2 ubuntu ubuntu 65 Sep 4 16:55 reference-images\\n-rw-r--r-- 1 ubuntu ubuntu 1054283 Sep 4 16:55 task008_start.blend\\n\\n/home/ubuntu/task/input/reference-images:\\ntotal 672\\ndrwxr-xr-x 2 ubuntu ubuntu 65 Sep 4 16:55 .\\ndrwxr-xr-x 1 ubuntu ubuntu 69 Sep 4 16:55 ..\\n-rw-r--r-- 1 ubuntu ubuntu 340834 Sep 4 16:55 hair_solution_fr1.png\\n-rw-r--r-- 1 ubuntu ubuntu 340447 Sep 4 16:55 hair_solution_fr30.png\\n\\n/home/ubuntu/task/output:\\ntotal 392\\ndrwxr-xr-x 3 ubuntu ubuntu 55 Aug 19 05:01 .\\ndrwxr-xr-x 1 ubuntu ubuntu 27 Aug 7 05:45 ..\\n-rw-r--r-- 1 ubuntu ubuntu 400388 Aug 19 05:01 scene.blend\\ndrwxr-xr-x 2 ubuntu ubuntu 10 Aug 7 05:45 submission\\n/usr/local/bin/blender\\n48\\n total used free shared buff/cache available\\nMem: 377 70 139 2 167 295\\nSwap: 0 0 0\\n\",\"stderr\":\"\",\"timed_out\":false,\"stdout_truncated\":false,\"stderr_truncated\":false}"}]},"metrics":{"prompt_tokens":2,"completion_tokens":1008,"cached_tokens":2617}},{"step_id":3,"timestamp":"2026-09-04T16:56:10.327310+00:00","source":"agent","model_name":"claude-opus-5","message":"Analysis: Bash works.

Interpolated children add readable clumps, curl (Kink = Curl) and roughness rather than a wet, helmet-like sheet.\n- **Viewport children**: Display Amount 10 with Render Amount 100 — exactly 10% in the viewport while the full rendered child density is retained.\n- **Material**: `hair_brown`, a Principled Hair BSDF (melanin-based warm brown) assigned as the particle system's material.\n- **Dynamics**: hair dynamics enabled with gravity, a cached point range of 1–30, and `head` given a Collision modifier.
