edit: got it working.
I think ABCExport only has a MEL command line interface so I’m trying to use this command to export Alembic but it’s not working. The command line spits this out for the manual export of selected (the node listed as “test” in the command):
AbcExport -j "-frameRange 1 15 -noNormals -uvWrite -root test -file /Users/beige/Desktop/test3.abc";
but it gives an error for this setup that should produce the same output:
mel.eval('AbcExport -j "-frameRange 1 15 -noNormals -uvWrite -file -root '+mySelection+' '+(projPath + "MariMe/" + meshID+ ".abc")+'"')
