#Opacity
>> What I did was render a white ball…
John, try lofting a long twisty "shaft" in the lofter. Mapping coords
on. Length repeat 1. Perimeter repeat 1. Create an animated
opacity map that goes from all black to all white, over time. As
soon as the "beginning" of the shaft appears, so will a little of the
"end". It appears that texture filtering, smooths across the seam
from beginning to end ("wraps around").
See my note to Mike, where I left some suggestions. It's an odd problem that I
dealt with about a year ago. Rather than fighting for the "perfect" look, I
just hid the "glitch" as best I could and got on with the job.
