Back
i have been bugging paople about this for time!
i ended up with about 10 fractal shaders + marble + vein and loads of mixers
and stuff, and got 'close' to what
the Maya ocean shaders do (i rendered out these from maya, one layer at a
time, and approached it that way)
but the problem is the different 'types' of fractal shader WE DON'T HAVE!
come Montreal, it's an afternoons codeing to give us some decent fractal
noise shaders!
veroni etc....

/end rant
ps, even better, spend a week writing an out of the box ocean shader, and/or
i'll marry you all!

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:
http://colorshopvfx.dk/XSI/fractal_displace_comparison.jpg
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!
