Error while Assigning paths to SliceStacks

[hit-the-luke]

Hello,

I am new user of this package and I am trying to save my data in a similar format to the cube_gears_sliced.3mf from the 3mf examples, with the slice data in a seperate folder within the 3mf file. This is where i run into the following errror "Lib3MFException 5: Referenced model resource must not be in a different model."

I am Using Windows 10, Lib3MF version 2.1.1 and Python 3.7.4

I don't know if I am using the wrong function for the desired outcome or something else went wrong.

On a similar Issue I would also like to put each mesh into a different file referenced to by a main model. This I tried with PackagePart() getting unsettisfying results. But I am not sure if that is even ment to be possible with 3mf.

Find attached a python example Code (as txt as .py was not exepted) and its Output.

Lib3MF_Example.txt

thanks in advance
