If you've generated a colorful 3D model in Meshy and noticed it turns grey or monochrome when imported into Bambu Studio, here's what's happening — and how to fix it.

# Understanding the Issue

Meshy generates models with **PBR texture maps** — image files (Diffuse, Roughness, Metallic, Normal) that wrap around the geometry to produce realistic colors and surfaces in renderers, game engines, and AR viewers. These are **visual textures**, designed for on-screen rendering.

FDM multi-color printing works differently: the slicer needs **color-per-face assignments** baked into the model — each polygon is tagged with a filament color. Texture image files cannot be interpreted this way by slicers like Bambu Studio.

In short: the colors you see in Meshy's 3D viewer are texture-based renders, not multi-color print instructions. That's why Bambu Studio only shows the geometry.

## Does the export format matter?

| Format                                           | Carries textures? | Usable for multi-color FDM printing? |
| ------------------------------------------------ | ----------------- | ------------------------------------ |
| STL                                              | ❌                 | ❌                                    |
| OBJ + MTL + texture                              | ✅ (visual only)   | ❌                                    |
| GLB / FBX                                        | ✅ (visual only)   | ❌                                    |
| 3MF (from Meshy, geometry only)                  | ❌                 | ❌                                    |
| 3MF with color-per-face (e.g. from Bambu Studio) | ✅ (print-ready)   | ✅                                    |

No matter which format you export from Meshy, the texture data cannot be directly used for multi-color FDM printing.
