Don't recall if it was by PM, E-mail, or in a thread here somewhere.

I refer to it as 'shuffeling' or adding redundant verts to balance file sizes.

Importing the files into most 3D programs gets those thrown out as most programs optimize by default.

I remember you discussing about the importance of these "redundant vertices", though to be totally honest I never fully understood what's the point about them

Say we have 50 verts with their 50 normals.
But it has only 30 vts. (texture coords)
Faces don't matter as those are stored in a separate area.

GR2 stores with vt, vn, and vt in a structure.
So we run out of vt's!
TDW did some crazy stuff which does account for that but increases file size in a wild way.

So all you need to do is add to the vt count to have a balanced file.
They can be zero coords or re-use already used coords. It don't matter!
Now Exported meshes from a GR2 HAVE this extra info!
Once imported into say 3D Max? Max DUMPS the redundant stuff!
So an export with NO modifications to the file WILL NOT have the extra info.

That forces you to use TDW's strange import function and the result is a file MUCH larger then it needs to be.
I believe there's a 'clean' import or something? That sees the file as proper for import and no extra processing is needed.
Thus smaller file sizes.

Somewhere in the Exporter thread or else where I PROVED this and gave the answer!
I'll see if I still have objsort code and add to it to adjust for this.
