Not working: Blender 3.0, Houdini 19, Z-Brush 2022

[Kettenotter]

Have tried it with Blender, Houdini and Z-Brush... every single one gives me an error on copy to external. Not sure if paste from external would work.

Zbrush error:

Houdini error even thought I did select sop

Blender error:

Text version Houdini:

File "Export to external", line 4
   print "You need to have a SOP Selected that you want to export."
                                                                  ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("You need to have a SOP Selected that you want to export.")?

Text version Blender:

Python: Traceback (most recent call last):
