I'm afraid I'm unable to help you with that. However as I said before FIXT and Fo1 engine are a thing of the past now. Fo1 has been moved to more advanced Fo2 engine. It's still a work in progress, although If You can, You could contribute to that project. contact Lexx in 'Fallout et tu' thread in modding section. As For Your question.. well, I think Sduibek is the proper person to answer your question, however He's not around for quite some time.
