Hi, I'm working on a whale scene also. As far as getting it to work in Brye, I haven't gotten as far as you, so I took the scene to Director and added the whale in a separate sprite. That made things much easier, but not as realistic as I would like it to look. Doing it alone in Bryce would be great. I also found that recoloring each frame in Photoshop gave me much better color. My project still needs work, a lot of work, I've only produced about 50 seconds of a 1-1/5 film. I want to keep up with what you are doing with Bryce, so keep in touch.
