I'm sure that's not true for aircraft. Note the notch in the wing's shadow and the prop shadow.
I am using the original eclipse_col.srf in the aircraft folder for this model.
Take look at the col in an editor and you will see how different it is from the shadow.
Back to the ground objects...
I thought it may be related to the coll object so I have tried a few different coll models, including the full object, with no effect
I have compared the dat's & gob entries and see no significant differences.
The gob's are grouped together, so I guess they have the same "parent".
edit -----------------------------------
here's the same hangar with the coll removed...

Got it! dnm's cast shadows. srf's do not.
