Shape key deforms edit mode / object mode after editing basis I have rigged head mesh and body mesh with shape keys.

I edited head mesh's basis to match with body and then make shape key value 1.0 for both mesh.

In Edit mode, two meshes match with no problem, but in object mode the head mesh deforms a little bit off.

Edit Mode:


Object Mode:


I think it happens because I edited basis. How can I fix this to match both meshes after I export it?
Once Basis is deleted or edited, you will have to append an earlier saved version of the model and Join as Shapes.

Hopefully, you are doing incremental saves?

The only other option I can think of is to manually match the vertex positions, but using the 3d cursor for precision:


Select the body object > Edit Mode
Select the vertex Shift+S > Cursor to Selected, tab to Object mode
Select the head object > Edit Mode
Select the matching vertex Shift+S > Selection to Cursor
Repeat
