I just wanted to chime in to say I'm also having this problem. Just seems to be on the BMP-2M. From around 75m+ the model looks fine. Move in closer than that, it turns into a BMP-2.
Win7 Pro
AMD FX 8320 3.5ghz
GeForce GTX 760 driver 350.12
8 GB ram
On the workaround above. How do I "rezeplode" the 100c.brz file?
