in the editor spawn a large vehicle
move it to cast a shadow on the outside of a large tent on the airfield
dark shadow outside, feint on inside.

This is not how it would look in the real world, and the tactical advantage afforded to anyone inside the structure is small at best.

Also it's an immersion killer, at least for me. It should be at least as dark as the patches on the internal texture in this instance and adjusted appropriately elsewhere.

Easy fix, for a great effect!!!
