How to Prompt a Spline 3D Product Turntable Without Trademarks
Turntables fail when the model adds an LCD with a fake OS and a house logo the spec said to skip. Spline is not Blender and not Luma video. Dimensions, materials, and a 360 yaw are the brief.
The matching generator is the Spline 3D Product Turntable Prompt (No Trademarks) prompt. Browse related cards in the PromptDig library (Browse more prompts). When a filled run survives, share the version you actually use (Share a prompt).
Lock Spline and the units
Write a Spline 3D product turntable brief from a physical spec. No trademarks, no fake UI, no invented dimensions. Start by filling Inputs, not by asking the model to remember last week's run. If a field is blank, write NONE or NOT IN INPUTS and leave it blank through Generate. The card is built so the model cannot honestly invent a number, owner, URL, or command that you did not paste.
Paste these fields before you hit run:
Product dimensions, materials, color: [Product]
Spline features I will use (3D, materials, lighting, states): [Spline]
Turntable degrees, duration, easing: [Turn]
Camera and aspect: [Camera]
Environment (studio, HDRI named only if I own it): [Env]
What must not appear (logos, UI, brands): [BannedVisual]
Export I need (web embed, mp4, glTF): [Export]
Words I must not use: [Banned]
Whether the screen on the product is blank: [Screen]
Units: [Units]
That inventory is the honesty ledger. Anything that does not appear there is forbidden in the draft. If you catch yourself adding a nice-to-have after the run, you are no longer using the card. You are ghostwriting. Put the extra fact in Inputs and run again.
Model only the parts in the spec
Generate is numbered on purpose. Do not skip a step because the first paragraph looked done. The early steps exist to stop later prose from smuggling claims.
Walk the Generate list in order:
- Tool lock: Spline 3D scene. Refuse Blender bpy, Luma, Pika, Recraft.
- Honesty ledger: dimensions, materials, turn degrees, camera, export. Forbidden: logos, UI chrome, brands, dimensions not in Product.
- Scene graph: objects to model, named generically. Materials from Product only.
- Turntable: degrees, duration, easing from Turn. Loop yes/no only if Turn says so.
- Camera: aspect and height from Camera. No invented focal length unless Camera has it.
- Screen: if Screen says blank, no OS UI, no app screenshot, no trademarks on glass.
- Export notes: only Export formats. No invented bitrate.
- Compliance pass: quote Banned words, trademarked marks, fake UI. Cut them.
If a step asks for a version lock, quote the version from Inputs in the output. If a step asks for a refuse list, keep the refuse list in the published artifact, not in a sidebar you delete. Reviewers should see what the model was not allowed to do.
Keep glass blank if the device has no screen
Most failures are the same shape: a missing field gets a confident fill. A conversion rate appears. A Gradle task appears. A flash point appears. A caption appears on a job that asked for slide text only. Your review is to search the draft for numbers, names, and commands, then grep Inputs. No match means cut.
Honor the constraints as hard stops, not vibes:
- Spline 3D turntable brief. Not Blender, not Luma video, not Recraft.
- No trademarks, no celebrity props, no fake UI.
- Never invent a dimension or material.
- Units from Units only.
- No emojis.
When the card says not legal advice, not certification, not an exam dump, or not a caption engine, that sentence belongs at the top of the output. Deleting it to look more finished is how you inherit risk.
Export only the formats you asked for
Finish with the compliance pass the prompt already asks for. Quote the banned-word hits. Cut them. Print character counts when the job has a cap. Print word counts when the job has a budget. List gaps as gaps. Five missing facts are more useful than one smooth paragraph.
Tags on the card (spline 3d turntable, spline product scene, no trademarks) are a reminder of the job shape, not an invitation to wander into a neighboring cluster. If you need a different surface, open a different PromptDig card rather than stretching this one.
Fill the card, then run
Replace every bracket. Run on ChatGPT, Claude, or Gemini. Read the ledger first, then the artifact. If the model invents a commit, KPI, DOI, PEL, bid, or logo, discard the run. Tighten Inputs. Run again. Share the filled card that survived, not the first draft that sounded done.
