Hi Steve, maybe you are seeing some difference also due to styles/materials being supported now in MoI v2 which were not present in MoI v1.

That's about the only other thing that I can think of, it does take up extra space because there is now a style index stored for every polygon face.

So for example the storage for each display triangle is now 4 32-bit numbers instead of 3 32-bit numbers.
