can you please tell me how to add manually horizontal lines in each frame? 1)i am in Advanced Hugin mode 2)i add pictures (in the main "photo" window) 3)i usually click on "generate control points" (Hugin Cp Find mode) 4)and then i add/modify control points in the "control point" tab on high on the screen.
