I've been trying to find these rivers in a usgs data set, which is very difficult in tg2. there is several reason that find river like areas in a data set is hard todo, but two stick out, One water is always flat so the moving water which makes up the bulk of river doesn't exists I can only see the valley's fill up in the flat areas of the river. then two rivers only exists in valley like structure in the data so I have to wait for my preview to calculate enough micro triangles to even pic up a hint of the data, if i change the water level or move the camera I have to wait all over again. So I figured Hey if I Animate the water level I can just pull out the camera take a nap while its calculating and then from the animation I could pick the best water level and location to do my still shot rendering.
So i did a quick search and found several reference on this forum saying I just have to click the "S(curve) a" buttons next to the value i want to animate, and click "set animation key" however my "S(curve) a" buttons do not have that option, instead they only let me "import from text file". Im sure I just missed something stupid here any idea? we have the deep version of tg2 and its fully updated. This should be a fairly simply operation. the animation isnt going to be used for a final product i just need a way of seeing all my microtriangles at differnt water levels quickly.
