AI Model Generator for Roblox Low poly props, free

Describe a low poly prop for your experience and the AI builds it. Export FBX or OBJ and bring it into Roblox Studio with the 3D Importer as a MeshPart.

Free. Use your own Anthropic or OpenAI key.

Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.

Watch how it works

How it works

  1. 1. Describe it or add a photoType what you want in plain words, with sizes if you know them, or add a photo as a reference. Describe an object or a person.
  2. 2. The AI builds and checks itThe AI writes an OpenSCAD program for an object, or sets up the character generator for a person. It looks at six rendered views of the result and fixes what is wrong, up to five builds per message.
  3. 3. Refine and exportThe model opens in the viewer at real size. Ask for changes in the chat, move the sliders, then download it or pick a format from the Export menu.

Why make it with AI here

  • Creators can make custom props like signs, crates and furniture without learning Blender.
  • Ask for low poly and a set number of segments to stay under Roblox's mesh limits.
  • Colours come through so the prop looks right as soon as it is placed.

Getting the model into Roblox Studio

  1. Choose FBX (or OBJ) in the Export menu.
  2. In Roblox Studio, open the 3D Importer from the Home or Avatar tab and pick the file.
  3. Review the preview and warnings, then import it as a MeshPart.
  4. Scale it in Studio if needed, since Roblox measures in studs.

Roblox limits how many triangles a mesh may have, so keep props simple and curves low in segments. Studio warns about or rejects meshes that go over the limit.

Best export formats: FBX, OBJ

Good to know

Roblox avatars and layered clothing need special rigs and cages, which are not made here. Very curved or detailed props may hit Roblox's triangle limits.

Cost and privacy

You use your own Anthropic or OpenAI API key. It is stored only in your browser and sent only to that provider, which bills you directly: a model typically costs $0.05 to $0.30 at Standard quality and up to about $1 at Detailed, and Innerscene charges nothing. Your key and prompts are not sent to Innerscene; we record anonymous usage statistics such as the steps used, the model chosen, token counts, a cost estimate and whether a model was made.

Questions

▶Can AI make Roblox models?
Yes. It makes low poly props you export as FBX or OBJ and import into Roblox Studio.
▶How do I import it into Roblox Studio?
Use the 3D Importer, select the FBX or OBJ file and import it as a MeshPart.
▶Can it make Roblox avatars or UGC clothing?
No. Avatars and layered clothing need rigs and cages that this tool does not create.
▶Why is my mesh rejected?
It probably has too many triangles. Ask the AI for low poly with fewer segments and export again.
