The problem I had run into wasn't so much the "softness" of the opacity effect, but rather an apparent averaging/softening "wrapped around" from the left edge to the right. (Say for example that this represents frame 10 of an object with an animated opacity map that moves from left to right, full black becoming full white. In this case X= fully opaque and 0= fully transparent with 1-9 representing 10-90%. My object looks like this: XXXXXXXXX83000000000005X.) In the case where I lofted a circle along an S or G with mapping coords, the end of the S and G "appear" at the same time as the beginning. I have already finished the animation, and disguised the problem thru careful lighting and camera moves, but I did want to point it out to the originator of this thread as a potential problem in his project. In my case, I'd like the best solution for my own future reference. I love the effect. I suspect that my anim opac map has too low a resolution. I think I used 100 x 200 for a 100 frame effect. I have yet to send you my demo reel. It shows the lettering that gave me the grief. I'll send you a copy as soon as I append my latest work. Perhaps Bob Bennett still has the earlier copy I gave him at Autodesk University.
