Why a new 'merged' mesh is created when adding multiple loop cuts? I'm just introduced to loop cuts which add more vertices to the mesh but for me it seems to be creating a new 'merged' mesh.
I have no clue why especially since I can account for all the the meshes in the outliner and there doesnt appear to be an extra duplicate. Extruding seems to work just fine but loop cuts just do this when I try to transform the mesh after the loop cut.
Loop cuts are inserted using Ctrl+R or the Loop Cut tool in the Toolbar. Both tools are going to place an edge in a loop of faces and do not create any double geometry.
If you have double geometry after inserting a loopcut, it is there definitely not because of the loop cut, but because of some other mistake.
