OR, you could just model the Tranformers of your choice in Bryce! (grins) I have a model of the Robotech Veritech fighter. It's a 3ds file, Bryce takes it just fine. It is fully transformable. I didn't make the model, but it was free somewhere, I've used it for a few images in my gallery, because it rules! If you can't find anything, let me know, I'll email you the file!
