I'm trying to use the ExportAlembic.py example in Cinema 4D R20 but the application crashes.
The same example works in R19.
Doing it manually via
File > Export... > Alembic (*.abc) does work.
Tried in both Windows 10 and macOS.
While in macOs the crash reporter makes a log, in Windows, the applications freezes with "Preparing Project for Export" in the status bar.
