[WIP] Almagest. Strict Import for SH5.

I had to do some research but I'll explain how a 3D model is stored in a dat file.
I'd figured this out long ago but just some details I had forgotten.

I have a Template for 010 that I'd forgotten about so I used it to refresh my memory. I guess I'm getting old!

Anyway! Here's how a dat stores the information and how I figured it out.

All verts are stored in a chunk of information easy to follow with my Template.
As are Faces and texture coords. And here's where it gets tricky!
Any extra texture coords, for say the AO mapping, get stored right along with the Main objects coords in one chunk of data.

That's where the TMAP sections come in! They point to the Verts and the texture coords in the main chunk of data! So they are nothing more then faces calling the proper lines from the main chunk of data.

S3D just puts out a proper obj file on export then on import?
Just stacks everything in it's proper place.

How I do it is to export a 3D model as a rawchunk with S3D then run my Template. It takes a few minutes to look at things and see that texture coords are GREATER then the same obj files exported by S3D.

Should anyone want to see the Template and the files I worked with let me know.

SH5 does it a bit differently.
