Guys,Regarding the bleeding of terrain thru ground polygons/taxiways.I have seen this phenomenon (see pic) with some of the MS default taxiways. But, it seems even more present when I create my own with the SCASM taxiway commands.This example is with the default MS mesh (elevation points).Does anyone have any idea what might be causing it ? It seems like a Z-Buffer issue. I am curious as to any work arounds that might be available, either thru DirectX settings or SCASM commands.Thanks in advance for any explanations or advice,Allen

one way to fix it is to construct a runway in the offending area and give it a surface type of -1, this should make it invisible.B

I'll give that a try. Thanks BobAllen
