Im working on a buggy body. The problem is that I need a whole mesh UV for texturing. I made a plane mesh that I extruded and scaled to make thickness (had problems to use solidify. It was giving me zero thickness in some areas) Now I am stucked because I dont know how to mirror it and have it as the same mesh. Extrude now dont work probably as its not a plane anymore. Anyone can suggest me a way to get the best result? Im adding a photo of that model. Seam path is the axis of mirror.
Btw: As you can see on image there are some dotted lines (mesh of some unknown cube) in the body model. Whats that?
