stick that sword inside of a cube then add 3 or 4 radials ( 3 radials in a triangle in front. 4 radials up and above evenly) real low setting 3 to 5 and the fall off set at none. See what that looks like. can also change the ambiance and refration of the cube for diff affects. give it a shot. the pic in the link everything looks to uniformly lit. my 2 cents for what it's worth

"Reinstall Windows" is NOT a troubleshooting step.
