I seem to be having a problem where after unfolding UV's I can no longer select edges and therefore cant merge the UV edges unless I select them directly on the model, which is a pain to be honest? Hi everybody, I have the same problems in Maya 2015. I can-t select eny Edge on UV editor. Normally, when I open UV Editor, meshes UV are in white wireframe, but if I try to select edges by RMB/Edge, the all wireframe becomes blue and I can not to select any edge. It happens even if I re open scene and even if I don't have any Tools selected. (By the way, if I select a tool, I don't know how to deselect this tool to return to initial state...). Please help! Many thanks for a reply!
