Thanks-unfortunately this particular mesh has a glitch. It looks fine. However it has no lightning or whatever when it gets hit.
Then when it takes medium damage some faces collapse or cave. Wierd. Sometimes this is from a duplication problem but everything seems fine. Also my Lancer was using much of these parts and I finished later, yet it is fine. So I started swapping out parts 1 by 1 but no luck. Starting to belief that the file itself just got corrupted at somehow.
I spent more time trying to solve it-I could have rebuilt it from scratch. I am determined to get some sort of varient to the Lancer it might not look like this though. My enthusiasm has been zapped
This is what I get for hording them
