really nice castle. two things: 1. Nvidia GeForce2 MX/MX400 is a horrible card. Don't know if you've had problems with it, but it's a low end deal that will cause problems with graphics. 2. really large scenes are a pain and bryce will fool you in 1001 ways to make you think it crashed. in general, anything over 200mb is going to be a pain. try to layer the render.
