Lit and wireframe
There is no mix of the two.
If you want to see an object in wireframe along, open it in the mesh editor:
( double click )
You still get the wireframe of the sky though. If you don’t want that, you have to setup a preview without the sky, which you can do, but then the preview will look weird.
In the mesh editor, on the ‘preview’ tab, you can turn off the environment
and save this as a profile.
