UV Editor: Cannot move shells

[Anonymous]

I'm UV mapping a piece of terrain in the UV editor. It is split up into multiple UV shells.

I must have hit a hotkey, because now I cannot move, rotate or scale the shells when I select them. The gizmo just moves their pivot.

Have tried selecting and reselecting the transform tools, closing and reopening the UV editor, but none of this is helping.

Thanks in advance for any help

Hi @Anonymous 

It sounds like you enabled pivot editing. Try pressing the D key and see if this resets the tool back so you can move the shells.

Thanks for your response, but no this did not fix the solution.

I did not have the pivot tool selected in the main viewport and pressing D in the UV Editor has no effect.

Is there another different tool within the UV Editor that would do this?

Hi @Anonymous 

If that didn't fix it then this may be due to the poly size of the landscape. There have been some similar issues reported with the UV editor not working properly when dealing with millions of polygons. Is your scene this high poly?

The heaviest mesh I have in the scene is around 323k triangles, but the mesh that I am actually uv mapping is around 11k.

I don't think that the mesh scale or density is the problem, because I was able to go back to a previous save and continue UV mapping it.

I have also tried selecting verts, edges and UVs. They become highlighted but cannot be moved, rotated or scaled.

The mesh and its subobjects can be manipulated in the viewport, just not in the UV editor

Hi @Anonymous 

Hmm ok. Your UV's might be pinned, try using Unpin All. in the UV Toolkit go to Pinning->Unpin All.

Ughh, that was it. I never pin UVs.

Still no idea what key combination that I pressed, I couldn't find any that deal with pinning.

Thanks for your help

I am having the same problem everytime i try to move them they distort. I unpinned everything like you told the gentleman previous to no avail.

Delete the history on your object and freeze transformations before starting UV work.

[lwvelazquez]

Did all of that

Try changing the viewport to DirectX11, if that doesn't work you can zip the file here.
