I know from reading the other thread that a question was raised about how the information on mapping is stored in a dat file.
A dat with only 1 map channel is stored in a simple block of data.
When We add say an AO channel? A TMAP section is added to the dat.
I'll have to refresh my memory on how the TMAPs actually work since it's been so long since it had to be done by hex editing. (Pre 2007!)
BUT! Only faces and texture coords are saved to the TMAP sections if I am recalling correctly.
I actually still have a program from 'back in the day' that exports and imports the different TMAP channels. So one could change or add just a TMAP and not have to re-import the complete obj like S3D does.
