I GET HOT SPOTS IN MY ARCHITECTURAL ANIMATIONS AND CAN'T SEEM TO GET RID OF THEM NO MATTER WHAT I DO. I'VE TRIED MOVING MY SPOT LIGHTS FAR AWAY FROM THE OBJECTS AND INCREASING MY AMBIENT LIGHT TO 100 – TO NO AVAIL. ANY SUGGESTIONS, ANYBODY ? I'M GETTING QUITE DESPERATE ! PLEASE REFERENCE FILE X_R1.ZIP FOR 3DS PROJECT FILE AND TEXT. THANKS

Umeadi Your hotspot may be caused by an omni light being too close to the object. Ambient light should generally be kept to 10 or less and the ambient color of the material (keep it quite dark) can also have a profound effect on material hotspots. I'm heading out of the office, so can't dl the prj file right now. -Ted Boardman

<<I'VE TRIED MOVING MY SPOT LIGHTS FAR AWAY FROM THE OBJECTS>> This won't make any difference to the intensity of light cast on an object unless attenuation is on. Just turn down the intensity of the light/ <<AND INCREASING MY AMBIENT LIGHT TO 100>> Well that will surely kill any shadows but it won't reduce the hotspot problem. Just reduce Ambient to 10 then reduce all the spotlights and others as well. This will darken the scene and reduce the problem. More precisely you could reduce the intensity of those spotlights causing the particular hotspots. DaviD "a volcano is a hot spot" GouID

In addition to Ted's reply, check you shinny values in the material editor for the materials in question. Many of the material which are called "matte" have shinny values of 5 and 24. This can cause unanticipated hot spots as well. In many cases you may want to knock those values all the way down, or even push them both up. These low values can cause a very wide and broad "hot spot" Chris P.S. Avoid using all caps in your messages. All caps is called "computer screaming"!

Chis: Thanks for the advise on eliminating hot spots. I'll make the necessary adjustments in the material editor. Wow, I never thought of that! I'll avoid using caps in the future. I WAS really frustrated with the hot spot problem, and was SCREAMING inside. Appreciate the help guys!
