How to Reproduce:

• I created a small mesh I want to use as base for the retopo.
• With that mesh active in object mode I clicked on "Edit Active" in the RF menu.
• After a few seconds RF closed with the error (see above). A mirror modifier was added, the RF menu in the viewport disappeared. It does come back after restarting Blender in the 3D view, but got the same error when I tried again.

I don't want to post the file here but can send it by e-mail if needed.

thanks for the details, @ChristinaMcKay .

it looks like RF failed with a nodes modifier.

would you check if deleting the modifier works around the issue?

or, you can send the .blend file to [email protected], and I can run that and other tests here.

thanks for helping us debug this!

Thanks for the fast reply @vxlcoder

It is indeed the Auto Smooth Modifier. After applying it, RF works.
It would be better not getting an error when using the Auto smooth. I guess that will be a common problem for other users as well.

great! yeah, we'll look into why this is happening, and try to fix it. thanks again for reporting and helping! happy retopo'ing!
