Thanks Raa.
I'm almost certain that Mikhael is responsible for the geometry. There were a couple of texturing jobs done on it though, and I'm honestly not sure whose this is. That's where redmenace would know, as he's the one who got the mapped file in the first place. That said, this is perhaps the coolest-looking HTL upgrade I've ever had the luxury of using. It's a bit resource-intensive, but it's an awesome piece of work.
Anyway, I went ahead and broke off chunks to use as debris, and rebuilt the LODs partly. The file "beamsaber_fixed.POF" is a variant with the cannon pointing forward; any future campaigns should probably use this since you can point it where it needs to go much more easily. Oh, for those who downloaded the file last night: you got the full deal, but for whatever reason the debris object list got erased. So all of the debris were in the model, but would never have rendered.
