Yes. You need the second set of Texcoords in the GR2 file for the AO.
There is no built in Structure in the granny2.dll to read them though.
So if your useing the same calls as used by Quark (Which came from gr2.Decode by the way) to read the PrimaryVertexData you'll never access them.
By-passing the granny2.dll allows reading (and writeing) them.
Here's the King George's AO texcoords extracted. (no granny2.dll was harmed during the extraction!
).
For the Normals, it uses the first Texcoords set.
But you need to write the code to implement Normals.
One good thing? You don't need to write the code to calculate the Normals, Tangents, or Bitangents.
Those are already in the PrimaryVertexData.
So you only need to read them.
