Import multi-color GLB file into PrusaSlicer for MMU

I'd like to print a protein structure using my MMU. The model I have has all of the color information in a GLB file format. When I convert it to an STL, it loses the color information, and this won't be an easy thing to print in PrusaSlicer.

Is there a method for importing color models into PrusaSlicer where the color information can be maintained?

colour can't be maintained by any method that I know, but you could paint the single colour STL with the paint tool to approximate the colours  (there are more than five colours in the picture)
If printed, in the orientation it is currently in, you could swap out the yellow or red, for dark blue because the yellow and red end, before the dark blue starts

Color unfortunately cannot be saved in .stl format but perhaps you could switch out the material during the print or pick up a paintbrush!

 

At the very lease there are tools to easily, quickly, bulk convert to stl format from glb:

I presume the colours are software generated - instead of generating, say, blue use the same software to generate a GLB file of just that part which would be coloured blue; it does not need to be contiguous; then you then convert it to an STL file. Call it colour1.stl, now repeat for red as colour2.stl and so on.

As long as all the parts are generated from the same cartesian reference all the files can be loaded together as parts; assign each part to a different extruder and load the appropriate colours.

A current thread on a simpler version of the same problem:

Cheerio,
