Exporting 3D models from GR2

My first thought is D3DTADDRESS_WRAP
I have no idea how most of this works.
The 3D Engines I've been testing handle this aspect.
I noticed that some dats from GWX do not render in S3D also.
I never thought much about them till now.
The Whale from GWX renders black in S3D.
I saw that the UV stuff is displaced from standard.
But it renders fine in all versions of SH.

So if I go with the idea I need to center all Texcoords so S3D will render correctly,
I need to have a fuction that tests for conditions outside of the base TexCoords
as S3D understands them.

Now as I am only concerned with SH5 files?
I can pre scan them and code the functions to them.
The numbers of GR2 files with Meshes is limited in SH5.
Those are the only files I'm interested in right now.
It may be possible to filter the files by who created them.
Then apply checking functions and adjusting functions.

That leaves an exported obj file that shows properly in S3D and all other areas.

There may be some meshes that fall outside some speculated matrix though.
