OV-10A Bronco SF2

"Drop the folders into your SF2 mod folder and fly! It all set with the weapons, guns, sounds" Appreciate the work that you all do for free, but what is the mod folder? Doesn't exist in my version of SF2.

Sadly, there is a very unpleasant error. At certain angles, thin gray lines appear, stretching from the aircraft down to the ground, where its shadow is projected. There are holes in the 3d-skeleton of the aircraft - leakage of the shadows thru edges open on a mesh. So when a shadow is generated behind the model, glitches begin. It's very annoying as looking at the planes. Thus, the model needs repair in 3D Max.
