Aaargh... Pulling my fair out! I read someplace that saving to M3dImage + Paramerer (.m3i) preserved both image and parameters... Great!!!
Saved Fortress....
Went to reopen it.... Only image opens and Formula error for ALL the params.

Glad I c&p'd the params to my posting so... 

 

Where are the params gone???

 

UPDATE... Nope... I'lied...

C&P'd the 'params' from the image posting here back into the app...same thing Formula missing???? That's that then for Fortress!
