Hi,
S22.016(RC)
I am attempting to make an automated Alembic thinking particle exporter, and I have run into an issue where setting the export options does not work.
Copying directly from the dev example here:
https://github.com/PluginCafe/cinema4d_py_sdk_extended/blob/master/scripts/03_application_development/files_media/export_alembic_r14.py
and only changing a few of the export options. Script does not work properly, as the resulting .abc file exported DOES contain all objects (not just the selection, as specified), and does NOT contain the particles.
Please advise me.
Thank you.
