Aloha maya freaks! =)

Yesterday I plaed with maya nodes and found Height Field, i think it was called. Anyway for you that havn't seen that node it's a way of seeing the displacement of a sertain shader in realtime. At first when I saw it it blew me away, totaly! I assagned a noisa and animated it, wohoa, live water =D. But anyway when I tryed to render it I couldn't see anything. After that I looked in the help file and it said something like this "The height field node can't bee seen in renderings" , DOH!!
Anyway =), I looked in the examples for fluid effects in maya and saw a nice example of the height field.
There was 2 planes, one nurbs plane, and the height field plane.
And when you rendered you saw exactly what you saw on the height field! I looked at the connections and it was a bit complex, and I couldnt find any "Assing-plane-to-heightfield-button". Is there any scripts/plugins for that, (may be it don't have to be a height plane, maybe do the same thing on a character?), or should I do a script on my own? =)

try to connect the output of the height field node into the displacement input for your nurbs plane. another good idea is to connect the resolution of the height field with the uv-tesselation attributes of your nurbs plane. in that way you easily can control the accuracy of the displacement. but be careful with those values. remember that those define how many times each surfacePatch is subdivided at render time.
cheers, tom.
