I'll try and older one, I tried going back to the previous 2 versions to the same result. Maybe I'll go way back and see if that works. Right now it seems like the issue is primarily on the Keyshot side of things importing FBX. The same files are tested and working when importing into CreoView, Max, Rhino, and Maya - Keyshot is the only one that struggles to open it. However, if I import into those other programs and then export an FBX from them, it will import into Keyshot just fine. So right now that's my workaround. Seems like there is 1 small thing that Keyshot isn't able to handle, but everyone else is able to and as a result they can rectify it for Keyshot.
