What size is have you asked for the shadow map in the lights, I default to 1000 and sometimes I get the memory message. Also how many lights 3 or more? Also have had trouble with allies beautiful hair - not least the xyz coordinates. It may all be a mac thing, I run on Powerbook G3 300 alas which seems to eat most items. haven't had a problem with different size bodies, yet. Just downloaded 4.02. You could render he fairies seperately and paste to background? Nice work
