Hi Graig,
Um, actually from what I've seen, the ray-traced spotlights will probably only
be used on a very specific basis, so I wouldn't characterize them as really
"slowing down" the renderer on a general basis. When you consider the speed is
quite a bit faster than r2 on AA/High and the quality is WAY better, this is
where the speed-up is evident. Although I haven't done a ton of architectural
stuff, I would theorize that in many cases, the Spotlight Overshoot function is
gonna be a very viable option, especially for animations. When you REALLY need
absolutely perfect, sharp shadows (mostly for stills, I'd guess), the ray-trace
function will be a great tool to have. The bottom line is this: Everyone now
has MANY more lighting options with which to tailor their scene in the way that
best applies to their job at hand — a true hallmark of an exteremely versatile
production renderer!
