  "instruction": "Retopology Target-Count Decimation `/home/user/Desktop/scene.blend` contains a single dense mesh object `HighPoly`, a closed-manifold sphere-like surface with far more geometry than needed. Launch Blender by running `blender` from a terminal. For this workflow, use `/opt/blender/blender` for Blender command-line or background runs when working on `scene.blend`.\n\nCreate a new mesh object named `LowPoly` at the world origin, and save the result as `/home/user/Desktop/answer.blend`. ## Requirements 1. Output scene contains exactly one mesh object, named `LowPoly`; `HighPoly` is not present. 2. `LowPoly.location` is (0, 0, 0) within 1e-4 per axis. 3. `LowPoly` has no modifiers (the simplification is baked into the mesh). 4. `LowPoly`'s face count is in [950, 1050] — reduce face count to approximately 1000 (tolerance ±5%). 5. `LowPoly` is closed-manifold: every edge is shared by exactly two faces. 6. `LowPoly` has no loose vertices and no loose edges. 7. The axis-aligned bounding box of `LowPoly`'s vertex coordinates matches `HighPoly`'s bbox within 5% relative difference per axis. 8. `LowPoly`'s unsigned volume is within 15% of `HighPoly`'s (shape approximately preserved). The output must hold only the retopologised mesh at origin with a clean modifier stack.",
