Kyle thanks for the reply, This condition of the one harsh light is in the shaded viewport . I tried adding a new light that does show up in the rendered view port. but that had no effect on the fixing the problem with my shaded view port ?
play with your lighting style for shaded mode- You can use scene lighting if you want to see the lights you have set up.
fwiw, I use custom lighting for my shaded mode then use scene lighting for my rendered mode, that gives you some nice clean options for viewing rhino while modeling, and gives you a decent look at your light set up in rendered mode.
Thanks again kyle, I found when I reset my ambient color to back , which was where it was original, the problem went away. Some kind of glitch I guess.
