Hi ref,

I know that the devs are using 3dsmax and as I first started working on the dat files in March 2005, I found alot of similarities between the 3d models in the dat files and the 3ds fileformat.
But none of the chunks of a 3ds file have a structure size as the TMAP has.
Based on the name I would guess it´s an additional texture map (for each triangle one RGB value - but I never heard of a game using 48bit textures)

There is really just one thing left I think the TMAP is for and that´s SmoothingGroups but I can´t figure out how the 3 unsigned shortints or 6 bytes should built such a group and futhermore why each triangle of the mesh needs to be in this group...

Did anyone tried to delete the TMAP section of an unit and compared the both visual appearances in the game? Maybe that´s one hint... (I´m asking, because I can´t test any longer - I´m nearly 1000 miles away from my copy

)
