@Nicehatfox@RealSpaceJunk Generally I find that a region of reflected hard-light aberrates toward red on the boundary facing away from a light source, and toward blue on the boundary facing toward a light source
@Nicehatfox@RealSpaceJunk I got the shadow from the ball on the reflected region of light on the table by placing the ball shadow on top of the light in a separate group and changing the blending mode to "erase." This let me move the RGB channel layers into the shadow without a black shape obstructing it
