Alex.. Every time I see an Orbital or Roche image I'm aware that I'm not close to mastering everything that the current Bryce has to offer... But the render times! I thought that Bryce Lighning might be the answer - I have a spare machine... But no, read the details - two machines takes longer than a single machine because of the networking protocal overhead... From comments at the Bryce forum at Daz, 3 machines is little better. :-( Hey ho - and sorry everyone for the general grumpiness of my posts. Its cold and wet here in Paris, and I'm stuck in Excel preparing my business review for last quarter. :-( Garry
