Currently there are two approaches:
-making it all 3d. Means that signs, symbols lines are mostly done with
3d-objects. Good example the 787-display
-using 2d-layers. Syd is using this approach on his 777 but it does have
problems on some hardware- some layers disappear and are not visible and shines
trough other objects.
The second approach seems to be easier for me as modeler, I only have to make
the textures, but the current issues prevented my from using this method yet.
