f4dc9f9d68Short description of error
I have pretty simple geometry. And Blender can't unfold it in UV correctly.
Exact steps for others to reproduce the error
Select the mesh - right click on mech
Enter edit mode - press Tab
Select all faces - press A
Make Unwrap - press U then select unwrap in popup menu
Change to any of two Methods in Unwrap settings window
See incorrect UVs in UV editor

If I understand correctly, this seems to be a selection/syncing problem of the UVEditor not selecting all UVs even if all are faces/verts are selected in the 3D view edit mode.
Unwrap itself seems to go fine if you go the extra mile and make sure you have all UVs really selected.
(so go into editmode, select all, go to UVEditor, select all again [selection should actually grow in your case test file], then unwrap)
Anyways, will have a look at code tomorrow (because this should work)

As of
3a1e9b9997e33c059d08138da707ac16490fddf7, UV selection syncing issues should be fixed.I tried to redo the bug in
60d4d583760and wasn't able to (changing settings always updates).Changed status from 'Open' to: 'Resolved'
Not sure what went wrong in my previous test, but I can also confirm selection syncing is working now
So as long as the
Keep UV and edit mode selection in syncis turned on it should work well and unwrap should go fine.@ogneed-2 : Could you also confirm? (Feel free to reopen if issues persist, closing for now...)
Hi guys!
I just checked UV mapping -> Unwrap in last oficial Alpha — blender-2.80-55e3c17ccc1-win64.zip
Edit mode -> Select all faces ->UV mapping -> Unwrap
Now i see only thin UV line. I tried in all combination of the Angle Based\Conformal\Sync selection mode
Cannot reproduce, working fine here...
sorry for annoying you but take a look please https://yadi.sk/i/TpPjk-zzpGnbcA

I remember running into something similar. It was as if uv unwrap wouldn’t re-run if I already had a UV.
I reopened but I‘m yet to test the file and its reproduction steps, but the video matches what I ran into before. I will claim it, but @lichtwerk feel free to tackle it.
I've checked in last build (Hash:
134db5618a)All works fine for now. Thank you guys! You all doing great job!
