which, in doing a scene with no lites and a glowing posersurface, what I'm finding is that FFRender is interpolating wrong (or not interpolating at all) when doing GI bounces. this means that, as one adds more and more GIbounces, the splotchies keep increasing and getting worse. it was the same in poser 7, unfortunately. adding directional lites and limiting GIbounces to 3 (hard-coded into the first release of poser 7) makes the effect much less noticeable.
