Hey, thanks again for keeping the conversation alive 
Thanks for posting your code. I tried it, but did not have any success. It imported all of the grooms in the directory, but did not apply any conversion settings.
Thanks for posting your GUI import conversion settings, but I’m pretty sure those ones only apply to FBX import. I believe the only way to see the Groom Import Options dialog is by manually importing a groom. Would you be able to test that for me? Could you try to manually import a groom In order to see the Groom Import Options dialog? I need to know that your options for conversion settings are not affecting anything you are doing through code. If you find values, set them back to defaults (rotation 0, 0, 0; scale 1, 1, 1) and try your code again and let me know what you find.
I really appreciate your time and patience on this. This is driving me crazy.
