I see your point, afreaginname. True… true. Generally, we are talking about face normals, and it was good of you to point out faces does not necessarily equal face normals.
I wanted to see if I could replicate your “million-pieces” Genesis, and in my mind I thought it had to be something you were doing with DS export parameters. I was wrong, and I was successful in achieving the million pieces Genesis in Hex.
I never encountered this before, because I have never used this avenue with Genesis and Hex. Using default export settings in DS, and straight import into Hex does yield an exploded parts Genesis. The sizing is as expected. Roughly ten times that of using the bridge.
Here’s what I find interesting though; I import the exact same Genesis mesh into Wings3D, and it is one solid mesh model (just like in DS). Even further, if I use a mesh separation command the entire body mesh remains unaffected, and only face attributes are exploded/separated (teeth, gums, lashes, eyes, etc.).
I took the experiment one step further to see the results of importing the same mesh into Metasequoia. Same as W3D. One solid mesh. Although, the default import for Metaseq creates Genesis at a very small scale compared to the other two programs.
I think there must be something in the Hexagon import module that separates the internal grouping (even though W3D does not even identify this grouping in the OBJ code) within Genesis. I only used the default import settings.
The Hex/DS bridge does not do this, and Genesis is sent over as a solid mesh as it should be. Which is much easier on the whole morphing of Genesis endeavors.
Below are five pics showing the differences I found using the different software. Notice the default grid and Genesis relationship in the different pics for sizing:
