Well, you can unload any object you want to, not automatically though.
After you have rendered out the first 100 frames, goto the Objects screen and
choose the object you want to remove; then just hit Clear Object. You'll
also want to go into the Images screen and remove any uneeded images as well.
I think by setting the object's disolve to 0% Lightwave will
ignore the rendering of the object completely, but I don't think it will
be any faster if it is already out of the camera's view, and its images
will still take up RAM. Could be wrong though, as I've never tested this.

PS: Make sure you don't accidently save over the scene after you've
removed the object. It's an easy and painful mistake to make, hehe.
