well... here I am again... my first anim with the bouncing sailboat went fine. this time I merely put a tree on a plain, set the wind to blow, and moved the camera through it. 0-14 frames, 3 seconds long. set to 'final' render. I have 30 gigs free on my hard drive, but I get an error, writing to something to the order of error writing to c; vue; anim; tree, please check avail disc space and try again.... I went in and flushed the history... NOW... what have I done wrong!??? thanks again for your patience. furrtig
