shadow? problem in bulldozer

[Robb_ 38]

Hey there, I have this weird shadow problem or something when i zoom into my model in bulldozer. Here's a few pics

 

 

 

 

 

Looks fine when i'm zoomed out far enough

 

 

 

Anyone know what the problem is? Could it have something to do with my geometry lod? I have to redo mine. Was just testing to see if i could get the whole thing in arma, I put the ship into 4 separate models and using proxies to attach them. At the moment i only have one view lod, one shadow volume, geometry( needs to be redone) and a roadway.

Buggy shadow LOD, it needs to have a closed mesh, sharp and triangulated faces.

Ah forgot to triangulate the faces, worked fine after that. Thanks.
