OK, this part is only rendered when ungrouped! Is this a known issue?
I'm using Vray
cool model! great attention to detail. I'm a big fan of post-pro so I'd touch the levels up a bit, get the whole range of greys.
about the grouping, I found out vray ignores groups inside groups, they just dissapear. The answer is either to explode, or to make components, which vray does render if they are inside others.
