which, thx fr yr work on the blog/dummies thread. I think what is happening with bill's room lit by a glowing plane:  GIbounces occur even in the absence of directional lites, but it appears that a low-poly-density flat posersurface requires higher numSamples and lower ISS than a curved posersurface with hi-poly-density. 

thus they either hafta fix it so the flat surface and the curved surface get assigned different variables somehow, or they hafta fix it so that the flat surface doesn't generate such large errors in their calculations. 

to increase samples to 100K and to decrease ISS to 4 might give fewer and smaller blotches, but it shouldn't be necessary when a curved posersurface can have an artifact-free surface at much less extreme values, in the case where the only illumination is a glowing posersurface.
