- I can't help you with FRED (I use ProControl myself), but I can give you
- an alternative if you can't find the answer soon enough for your
- project...
-
- Simply set LightWave to import the three animations as image sequences,
- and then set the video sequence as Background (Effects panel) and the logo as
- Foreground, with the alphas as Alpha, and the output resolution to match your
- desired level. This will do the trick. (It's how I remove lens flares
- from past the
- edges of objects to be keyed over video/gfx backgrounds in our VR systems.
- Big black halos off the edges of an object around flares can be stoopid
- looking...)
-
- One of the odd, but nice, things about LightWave is that it actually serves
- as a decent image processor. And you can use it to build any kind of 3D
- razzle-
- dazzle transitions you want, just by mapping the A sequence onto flat
- objects and
- animating /morphing/dissolving/fading/exploding into B sequence like mad....
