I teach an animation class and want a short demo clip for my slides that shows how a mechanical linkage drives a whole sequence of motion — done as a retro-industrial kinetic-typography piece I can break down step by step. An old brass-and-steel machine picks up, flips and assembles scattered 3D letters one by one into the word MOMENTUM, then locks them into a title card. The mechanism is really the point, so students need to follow it layer by layer: a same-module gear train (a 400mm main gear plus several 60–200mm driven gears meshing correctly), two camshafts driving reciprocating push rods, a 2m conveyor feeding in the letter blanks, and two three-joint robotic arms doing the pick-and-place. The gear rotation, rod strokes and arm motions have to sync up in time so I can pause and explain each stage. Letters are bold sans-serif, 0.5m tall, extruded 0.15m with an 8mm bevel, ending up evenly spaced in a single row; the base is a 4m×1.4m dark wooden bench, with rails, rivets and similar retro-industrial details. Materials: brass worn and lightly oxidized, steel in cool grey with clear-coat highlights, matte wood. Warm workshop lighting — a key with a cool rim and ambient fill, plus an interior HDRI. Camera pushes in low then slowly orbits, 35mm, shallow depth of field. Main thing: the drive chain mustn't block itself and each part should stay clearly separable for teaching. Render in Cycles at 1920×1080, 25fps, 8 seconds (200 frames), with adaptive sampling and motion blur; give me a PNG sequence plus a composited MP4, and save the project as a.blend so I can tweak it later.

本次运行附加的执行指令

这是自建 harness 传给两模型的共同执行指令，不属于原始题目。CPU 设置与个别原题 GPU 要求之间的差异，详见主页说明。

Complete the Blender creation task in /workspace/inputs/query.txt using all declared references and attachments in /workspace/inputs/input.json. Read the reference images with Read; for video, extract and inspect frames with ffmpeg and Read. Blender 4.2.10 is available as `blender` or /runtime/blender/blender. Python with Pillow/NumPy is available as `python`. You can write and run bpy scripts with background Blender. This machine uses CPU Cycles; use 8 threads, and inspect your renders before finishing. You have an 8-hour time budget. Fulfil the original requested deliverables, including animations and resolutions where specified. Save the editable primary project to /workspace/exports/final.blend, with requested images/videos and all texture dependencies inside /workspace/exports using relative paths or packed assets. Put temporary scripts and previews under /workspace/work. Do not finish while required rendering jobs are still running. Use only the provided task inputs, your tools, and your own creation work; evaluation is separate.
