Non-Human Spaceship

WIP Non-Human battle ship. most rendered in Blender 2.61


I tried to make some animations with this ship, but Blender keeps crashing after few frames.

When Blender crashes over a few frames of animation and you are unable to solve the cause, perhaps render animation as a series of stills (I use png). This way, when Blender crashes, you at least have the frames up to that point, and can continue from where you left off, adding in any missing frames at the end (standard studio practice where nodes may go down in a renderfarm).
When you have all the frames rendered, then create the avi using the Video Sequence Editor. Low likelihood of crashing there and very fast to make the final movie.
