Short description of error
Options to "Mark Seams" and "Mark Sharp" in Bevel options does nothing
Exact steps for others to reproduce the error
I believe the options are somewhat mis-named. They do not "mark" geometry as seam/sharp if the original edges were not already marked. They will "maintain" the seam/sharp of the edge that you bevel... in various ways that I cannot explain. It's worked like this for as far back as I have readily on hand - 2.93 LTS.
Check the manual as well, though it doesn't explain much what "maintain" actually means:
https://docs.blender.org/manual/en/4.0/modeling/meshes/editing/edge/bevel.html#options
CC @howardt
Yes, the option affects existing seams and sharp edges. Also see: #99620
Will confirm since the description and tooltip of properties is not very clear.
Ohh wow. Yeah that's very confusing. So it essentially just retains the existing seams? So I guess "Retain Seams/Sharp" is a more accurate name?
Also, it should also be renamed in the Bevel Modifier, as it's called "Mark" there too.
On that note, it might still be broken because unchecking the box still retains the existing seam?
As far as I understand from code, these toggles just extends the existing seam/sharp edge marking along the beveled edges. Don't think unchecking should clear existing seam.
@PratikPB2123 no my point is that unchecked or checked makes no difference. Even if unchecked it extends the existing seam/sharp edge marking along the bevelled edge.
Hi, I do notice significant difference with and without "Seam" toggle
Maybe I did not exactly understand the recent problem you've mentioned or the issue is replicable with particular mesh? :)
Ahh okay. It behaves differently than I thought. Thanks for explaining.
In that case I guess this is not a bug. Though in my humble opinion it should definitely be renamed "Retain" Seams/Sharps. On twitter others also assumed it was broken.
I wrote a report about this few months ago #105429
Until the new Bevel #98674 (which seemingly will not have those specific options in favor of node-based workflow) arrives, I think renaming them might be a good way to go.
Thanks @persun , I'll close this as duplicate.
@AndrewPrice , please subscribe #105429 to receive further updates :)
This will be handled in #105429
