>However, the texture vertices threw me for a loop. I look at the numbers, they use a different unit system or scale than everything else,
Yup, you're right about that. The texture vertex units can be considered as pixels where 0,0 is in the upper left of the texture. +X goes to the right one unit perpixel, and +Y goes down one unit perpixel.. But a terxture is infinentyl tileable so negative units and "oversized" units are allowed.
> also I looked for the similarities that I found among the normal vertices, but couldn't recognize any. There are the same number of vertices, but I can't make any sense of it.
Vertex normals are a "normalized" (scaled to 1) vector that discribes the way a vertex "faces". This is done by averaging the normals of all the faces that use the vertex.
If you want, I'll tell you how to calculate these -- but I REALLY don't reccomend learning (you would just endup hating me, it would get ugly)!
