More about my morphing dilema. I'm creating a countdown. Each number begins as an extruded full screen rectangle which over 30 frames morphs into the number 8, for example. As the finished *8 moves off screen th what had been the background rectangle morphs into the number 7, etc… Now what I wanted was the effect of having the standard movie countdown [ie;circle with sweeping hand] projected onto these objectes. I had thought that I could save the intermediate steps of the morph and back in editor apply the same mapping coordinates to all of them, then in the keyframer the animation would just be moving/replacing one object with the next every frame. I hope this clarifies the problem. It seems like the same or similar approach that generates ripples could be applied here. An Process in which you can specify a start shape and end shape and then let the process generate the in betweens over a given number of steps. Andy

Andy, First, all mapping coordinates for morphing objects are only taken off of the primary morph source. This means that even if you COULD save intermediate morph positions, that wouldn't solve your problem since their mapping coords would be ignored. The only thing that morph targets provide is 3D position data for the vertex/face list. Second, by trying to morph the endcaps of text from/to such disparate positions, you may be asking for trouble. Since morphing distorts the endcaps of objects, you may get smoothing group discontinuities on your morph target. The best way to avoid this in your case would be to START with the text and end with the rectangle, and just render it backwards. That may diminish some of the discontinuities. Regarding your idea of having the circle w/sweeping hand projected over the objects… I'd do that by just making a layer in Animator Pro of the animated circle, and compositing it over the geometry in Video Post using the Pseudo Alpha option to blend the edges. It would give your countdown a very dimensional "Paintbox" look. – G
