Hello,
My first post here, I can’t seem to find the answer to this in Wiki or on the forum.
I am attempting my first decent size model, The Gloster E28/39 Pioneer jet aircraft. I modelled one side of the aircraft then duplicated it, “mesh” menu then shift D. The duplicated portion was then mirrored (CTRL-M) and attached to the original, opposite side of the model. Before going further I decided to try applying a map texture to it. When I went into “UV face select” mode the model looked a bit odd, the duplicate half was transparent. Selecting everything with “A” didn’'t help - see attached pic, however the LSCM unwrap did the job and gave me a mesh for both sides. I did a basic colouring of it, the surfaces cameout ok on the original side but inverted or not at all on the other side. I have played about with the Mesh-double side function and had a fiddle with verticals but to no effect… agh .
I tried this with a simple cube and got the same results.
