Texture Generator: test in Fast, finish in Quality with 4K PBR

The beta separates quick iteration from final polish: Fast generates 1K previews while Quality creates 4K PBR with roughness and metalness. Learn when to use each mode and which limits to avoid.

Quick answer

Use Fast to test the prompt and composition with a 1K diffuse texture; switch to Quality once the direction works and you need a 4K PBR texture. Quality adds color, roughness, and metalness maps, but takes about two minutes and can make small artifacts easier to see.

How to open it

  1. Select a MeshPart or a model made of multiple meshes. 2. Open Model > Texture, right-click and choose Generate > Texture, or run `/generate_texture` in Assistant with the mesh selected. 3. Describe the material, color, pattern, condition, and specific object parts. 4. Generate previews, choose Fast or Quality, and press Generate.

Why Fast should come first

Fast produces a 1K diffuse texture in under 30 seconds according to the documentation. It is the practical choice for correcting a prompt, comparing colors, and checking whether the selected orientation exposes the right part of the model. Once the result points in the right direction, repeat the prompt in Quality; do not expect an identical copy because every generation can vary.

What Quality produces

Quality generates a 4K PBR texture and applies it through a SurfaceAppearance inside the MeshPart. On multi-mesh models, every MeshPart receives its own texture and SurfaceAppearance. The improvement is easiest to see up close in patterns, damage, text, and surface variation.

Important limits

Do not request new geometry, particles, lighting, or camera changes: the generator only creates texture. It also does not support alpha channels for transparency, currently ignores normal-map details, and does not know Assistant's chat history; everything required must be written in the current prompt.

Time-wasting mistakes

Do not edit the object while generation is running because the process can fail. Avoid vague prompts such as “make it wood” when you need a specific species, tone, wear, or finish. For repeating floors, walls, or paths, Roblox recommends considering Material Generator instead of Texture Generator.

Success check

Quality generation completed correctly when the MeshPart contains a SurfaceAppearance and the result shows 4K PBR detail. If it is not usable, press Ctrl/Cmd + Z, keep a backup of the asset, and refine the prompt. Checklist: mesh selected → Fast previews → detailed prompt → Quality → inspect SurfaceAppearance.
