Ady, I looked for a model of the generator on Hoth but couldnt find anything that good. All I could find was a lego model of the generator. I found some cross sections of Echo base and the Ion canon, maybe someone has the actual book and knows if theres a cross section of the generator?

Also, if I remember correctly you use Adobe After Effects to correct light sabers. Im not sure if you ever heard of this plugin from Videocopolit (another forum member recommended it to me) so I messed around with it and I thought it may be useful, I just thought it may help out. (If you would like to try it I think you just click on "Project" and it automatically downloads the plugin)
