While there are only a handful common slicers, there are several hundred slicers in existence (some of them proprietary for specific industrial printers!) and technically every maker is its own slicer if they write the G-code manually. please add constraints.

That's a good point. Certainly there are slicers out there that don't even support .STLs at all...

Do all slicers handle multi object .STL files correctly for multi color printing?

I only have experience with PrusaSlicer, where if I have one .STL file containing multiple volumes, I can click a `Split to parts` button to then be able to change color of the individual volumes.

Do other slicer softwares handle this similarly or will I face a problem in other softwares?

I'm looking to upload my files for other people to print, and I would prefer to have 1 file per print. Can I upload these .STL files containing multiple volumes or should I rather upload separate .STLs?
