Ok, I've defined the locations where the Turm writing is allowed. They are left side:
7b_1_TWBFL = bottom forward left side (uses TGA 7b_1_TWBFL.tga)
7b_1_TWBML = bottom middle left side (uses TGA 7b_1_TWBML.tga)
7b_1_TWBBL = bottom back left side (uses TGA 7b_1_TWBBL.tga)
right side:
7b_1_TWBFR = bottom forward right side (uses TGA 7b_1_TWBFR.tga)
7b_1_TWBMR = bottom middle right side (uses TGA 7b_1_TWBMR.tga)
7b_1_TWBBR = bottom back right side (uses TGA 7b_1_TWBBR.tga)
and the front is 7b_1_TWFT = front top (uses TGA 7b_1_TWFT.tga)
the default TGA's packed into the .dat file are 2X2 'blank' transparent for all the above. If you want to use a location then you simply place the TGA for that panel in \data\Textures\TNormal\tex. If you don't override any of the default TGAs then your Turm looks just like stock (there's no change or impact to it).
For those worried about frame rates and texture sizes the 3D models are VERY simple models (one sided with the biggest 3D model having just a little over 30 vertices). The default textures are 2X2 in size thus VERY small byte wise for textures.
Now to decorate my Turm....
