In that case I'll have to start tweaking with isos, because I like lakes...

Where can I get (slightly readable) info about the distributions of sine
frequencies and directions?


I downloaded 'wt_water.pov' from your website but it doesn't seem to work in
PoV3.5 (release 7).
The parses stops here: #declare fnRMF=function{"ridgedMF",<0.07, 2.2,  7,
0.6, 0.9>}
because of this error: "Parse Error: Expected 'valid function expression', <
found instead"
Maybe I should download megapov for this to work?
