Starting RF on an existing mesh (Object mode > Edit Active) causes an error. It closes immediately, the existing mesh is mirrored.

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!

[ChristinaMcKay]

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.

[vxlcoder]

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

I've been trying to replicate this today, and even using Blender 4.2 and RetopoFlow 3.4.4, I haven't been able to get it to crash with Smooth by Angle modifiers on the target or source objects or on both. Has this still been an issue recently? If so, could you send us a file to look at? Thanks!

I have not been able to replicate this crash as well, with Blender 4.3 and RF 3.4.4, the modifier seems to not be affecting in my case. Is it probably a combination of conditions?

@ChristinaMcKay Hello, is this one still an issue in your end with latest RF version? (even with the modifier) In case you still trigger this crash, can you email us with some blend file where it triggers the crash consistently so we can analyze in deep? ([email protected]) Thank you!
