Hello Adam,
I hope you and your wife had a good time in Copenhagen!
I have tried it yes, but I'd rather not as it is likely to produce artifacts,
and besides it is a bit hard to do properly without post app style curve based
corrections. Actually a Math Exponent using Bias comes closest to what I want.
Still it can't really come up with the nice cauliflower style profile the
Combustion Turbulence produces :( I even tried Kim Aldis Turbulence node, which
produces nice irregularity but not the cauliflower style.
I tend to agree with Adrian on this - we need more fractal/noise/turbulence
shaders.

Hi there Morten,
Have you tried colour correction with the XSI fractals/clouds so that you
have more emphasised peaks?

Subject: Procedurals in XSI for creating waves?
I am working on creating ocean surfaces and for this particular thing I
would prefer to use procedurals in XSI for displacement. Trouble is it seems a
bit hard to get a good wave shape with the included procedurals. I have had
good succes with Combustion Turbulence and wonder if anyone here know how to
get that from the Rendertree?
See comparison here:

The Combustion Turbulence creates nice ridges for wavewcrests as seen to
the far left, and I seem to be unable to even get close with Fractals or Cloud
nodes.
Any suggestions?
TIA!
Best Regards
