RAD Games GR2 format for storing the 3D object files is basically an obj file.
The mystical part is how they did it. (To most people)
Why do they export with so many faces and verts and such?

That is where a FULL understanding of the obj file format comes in SO important!

RAD took full advantage of the format in a way that just confuses most!
I'll call it a shuffling of the deck type approach.
We take 2 decks with different faces, discard what we don't need, then shuffle the rest but in an organized way with a template of where each card is.

Each card is recorded in the Faces section of the obj format with a number.
Each number in the Faces section is a line number.
So if we want vert 75? It will be in that catalog as 75.
