Generate 3D Model

Beta — This feature is in beta. It's free to use during beta but rate-limited. Report issues on Discord.

Revix can generate 3D models from a text prompt using Roblox's Cube 3D foundation model. Ask for a prop, a weapon, a creature, a piece of furniture, or a full vehicle skeleton and it lands in your game with textures applied.

What it does

Behind the scenes Revix calls the generate_3d_model tool, which:

Sends your prompt to Cube 3D.

Receives a MeshPart with PBR textures.

Auto-uploads the mesh and every texture map to your Roblox inventory via AssetService:CreateAssetAsync so the asset survives Studio reloads.

Parents the part where you asked (default: Workspace).

Required Studio settings

Two settings must be on before 3D generation works correctly.

1. CreateAssetAsync Luau API (Beta Feature)

Open Roblox Studio.

Go to File → Beta Features.

Check CreateAssetAsync Luau API.

Restart Studio.

Without this, the upload step fails and the mesh reverts to a placeholder cube.

2. Allow EditableImage / EditableMesh APIs (Game Settings)

Open Roblox Studio.

Go to File → Game Settings → Security.

Toggle on Allow EditableImage / EditableMesh APIs.

Without this, textures are stripped silently — the mesh will appear but be untextured or solid-colored.

Choosing a schema

Cube 3D supports two output shapes:

Schema	Use for	Output
`Body1` (default)	Props, weapons, creatures, furniture, single-piece objects	One MeshPart with PBR textures
`Car5`	Cars, trucks, motorcycles, any wheeled vehicle	Multi-mesh skeleton with body + wheels

If you don't specify, Revix uses Body1. Ask for Car5 explicitly when you want a drivable-style vehicle skeleton.

How to use it

Just describe what you want.

text

Generate a 3D model of a medieval iron sword with a leather-wrapped handle.

text

Generate a Car5 model of a 1960s muscle car, deep red paint.

text

Generate a stylized low-poly mushroom with a glowing cap, place it in Workspace.RevixProps.

Be specific about style (low-poly, realistic, stylized), materials (iron, wood, gold), and color. Cube 3D is a foundation model — vague prompts give generic results.

Prefer the toolbox first

If a pre-made asset would do the job, Revix will usually try search_toolbox before generating from scratch. Toolbox assets are free, instant, and don't count against your generation quota. Generate from scratch only when nothing on the toolbox fits.

Limits and cost

Free during beta.
Rate-limited to 5 generations per minute per experience.
Generations are scoped to the experience you're working in.

Critical warning — never use ApplyMesh

Do not call MeshPart:ApplyMesh on a Cube 3D generated part. It wipes the PBR textures and leaves you with an untextured mesh. If you need to swap a Cube part's mesh, generate a new model instead.

If you ask Revix to "apply this mesh to that part" and the source part is a Cube 3D asset, it will refuse and suggest an alternative.

Troubleshooting

Mesh shows as a grey cube: the CreateAssetAsync Luau API beta feature is not enabled. Turn it on and re-generate.
Textures look wrong or missing after generation: the EditableImage / EditableMesh APIs toggle in Game Settings → Security is off. Enable it and re-generate. Also check that nobody called ApplyMesh on a Cube 3D part — that wipes textures permanently.
Rate-limited error: wait a minute. The 5-per-minute cap is per experience.
