hi Graham. FWIW, I found that increasing the tolerance, increasing the shadows relaxation and decreasing the minimum sample weight all seem to help/enable DBE to generate/accept samples in difficult images (might need big changes, eg I used 0.95, 8 and 0.1 on a recent problem image). The radius parameter also has an effect. I don't know enough to be sure that it would help, but it might be worth changing a few values if you have not already done so. regards Ray
