Ah, I didn’t try that. I kept using the Export button from the Tools palette.
I can see from the 3D Print Exporter tool tip that OBJ format does not support color, but STL does. I can now export and re-import an STL with color. Thanks!
However, now I come to the next problem. My original mesh is probably too big for the 3D printer. I can use Decimation Master to decimate it. But after decimation all the colors disappear. I tried using Project All. But the colors become blotchy. Seems like some of the vertices don’t get any projected colors.
So now my question is: What is the proper way to transfer polypaint to a decimated mesh?
