I textured an object for multicolor-3D-printing with Rhino 7. On the left you can see the textured Polysurface and on the right the mesh based on the Polysurface.
Then I exported the mesh as an .3mf-File. But the exported file is somehow broken: When reopening it with Rhino V7 it returns an empty scene. Using different types of Software (e.g. HP SmartStream 3D Build Manager) i get an Error.
An alternative file format would be .obj, but the resulting texture is also broken on the top and bottom:
Hello - if you Bake your original you can get a single bitmap (I would set the baked image size pretty high - say 2048 px by 2048) that is applied to the color slot in the material - export that to OBJ using the render mesh .
thanks for your reply! This works - at least for (poly)surfaces or extrusion - but sadly not for meshes.
However, we often need to color objects that are only available as mesh files (e.g. 3D scans). When exporting these as .obj files i always get some kind of artifacts.
