Overview
If you exported a 3MF file from Meshy but it shows up as a single flat gray color in Bambu Studio or OrcaSlicer instead of your textures and colors, it usually happens for one of these reasons:
Wrong export method — the model was exported with the standard 3MF export instead of the dedicated Multi-Color Print export.
Slicer view mode — the slicer is still showing the default single-filament or "Object" view rather than the "Color/Filament" view that shows painted colors.
Import method overwrote color data — double-clicking the 3MF to open it as a project can make the slicer override the color mapping instead of keeping it.
How to Fix It in Meshy
After generating and texturing your model, use Print → Multi-Color Print. It bakes your textured model into a color-segmented file that slicers can recognize.
See the Multi-Color Printing tutorial for the full guide.
How to Fix It in Bambu Studio / OrcaSlicer
Import the 3MF with File → Import → Import 3D Models instead of double-clicking to open it as a project.
Then switch the view mode at the top to Preview → Color. You'll see the multi-color breakdown instead of a flat gray model.
Multi-Color Print Export or Standard 3MF Export?
If you plan to print with multiple colors or filaments, always export with Print → Multi-Color Print, and import with File → Import → Import 3D Models in your slicer.
Standard 3MF export is only suitable if you don't need the color segmentation for printing.
FAQ
1. Can I get multi-color prints from a text prompt alone?
Yes, you can give your prompt to Meshy Agent and The Agent generates both the geometry and the texture, and you can then run the result through Print → Multi-Color Print just like an image-based model.
2. How many colors should I choose?
4 colors is a good starting point for most printers. Fewer colors print faster and more simply; more colors capture finer detail but add complexity for your slicer and printer.
3. Does this work with printers that don't have an AMS or multi-material unit?
Multi-color 3MF workflows are designed for AMS-style setups. On single-extruder printers without color-swapping hardware, you'll need to paint the print by hand or swap filament manually.
