Tools as reported by the server

• render_preview
  Show what a Blender scene looks like: a fast, low-cost preview render on a cloud GPU, back as an image in seconds. Typical requests: 'render this .blend', 'show me the scene', 'preview the turntable', 'I have no GPU', 'Blender is too slow on my laptop', 'Blenderでレンダリングして', 'GPUがない', 'ターンテーブル', '商品の3
• render_final
  Render the final frames or video of a Blender scene on cloud GPUs, after the user approved a preview: 'render the final', 'make the video', 'export the turntable MP4'. Call render_estimate first when the time or the free GPU time left (the welcome credit, or 2 preview GPU-minutes a day after it) is
• render_download
  Get the download links of a job (no key needed, valid about 24 hours; call again for fresh links while the files are kept, 24 h after last use or 7 days, normally, for paid keys) and show them to the user; in a terminal, fetch them with curl -o. A finished preview also comes back as an inline image.
• render_status
  Check a render job: status (queued / running / done / failed / canceled), frames done, the ETA (eta.human, including queue wait), files ready, Blender warnings, and the error with the log tail if it failed. Use it to report progress to the user; render_download(job_id, wait_seconds=45) waits and ret
• scene_info
  Read a Blender scene without rendering (a few seconds, no GPU time): cameras and the active one, frame range and fps, resolution, objects by type, lights, materials, whether it is animated, and missing linked files that would render pink. Use it for a .blend you did not write, or to check what a bpy
• render_estimate
  Estimate a render before starting it (no GPU time): GPU seconds, queue wait, the wall-clock time as text (estimate.human, e.g. 'about 3 minutes') and whether it fits the free GPU time left (the welcome credit, or 2 preview GPU-minutes a day after it) and the size limits. Call it before render_final
• render_info
  Check the connection and the service before rendering (read-only, no GPU time, no charge): the server URL, whether GPU workers are online, the queue length and expected wait, and this key's usage. Use it before the first render or when renders seem stuck, and to decide whether to route a render here
• asset_search
  Find free CC0 3D models, PBR textures or HDRIs on Poly Haven by words ('wooden chair', 'forest hdri') to furnish a scene without uploading files; no GPU time. For product shots of something the user has no model for: asset_search('<item>'), then render_preview(scene_script='import jr_assets; jr_asse
• render_share
  Publish a finished render as a public web page anyone with the link can open (for X, Discord or a client): the image or video, the render settings, an optional title and note, the user's request in their words (prompt), and the bpy script only if include_script=True. The page keeps its own copy of t
• render_unshare write/delete
  Take down the public share page of a job made with render_share. Effects: the page URL stops working, its copy of the image or video, the shared script and the shown request are deleted, and the page leaves the public gallery. This cannot be undone: sharing again makes a new page with a new URL. The
• render_cancel write/delete
  Stop a queued or running render job of this key (a j_... job, or a b_... job split into parts, which stops every part). Effects: queued frames are dropped; frames already rendered are charged and stay downloadable until the job expires; the rest of the GPU time held for the job is returned to the ke
• billing
  Check what this key can still render for free and its credit (no GPU time): the free GPU time left and when it expires or resets (each new key gets 100 JPY of GPU time free with no card (14 days) and 400 JPY more once the user saves a card on a page that charges nothing (once per card); after that,
• render_import_file
  Use a file the user attached in this chat (.blend, glTF/GLB, FBX, USD, OBJ, STL or a bpy .py script): JANCTION fetches it and makes it a scene of this account, and returns scene_id. Then call scene_info(scene_id=...) to read the cameras and frame range, and render_preview(scene_id=...) to see it. No
