I was playing around with the 1st generation Pessima and after finishing my modded mesh, there were noticeable lines in the areas that I changed (see picture). I was wondering if these lines will show up in Beam.NG, or what I need to do to fix them (Blender 2.83) and make it look like the rest of the part (no lines).
They are most probably edges on top of other edges. If so, you would have to remove the right edges for those lines to go away.
