Thanks for your feedback.
Unfortunately, we're unable to reproduce the issue.
Could you please try to uninstall Headshot and install it again, then generate the head and export the character again?
You can also upgrade the application to CC v4.2.
And make sure you're install "Full version" of Headshot, not the "Trial version".
If the problem persists, please take the screen video and upload it to Youtube or net drive and post the link in your next comment, feel free to set it as private message if you want.
Thank you for your patient.
Just tested base, with a character project from CC3 and was able to export to Marvelous Designer without issue.
More info needed. Are you able to export a base character before using headshot?
I think the steps you are using would be good to see if the issue can be reproduced.
