Only default items selected in scenery.cfg except for area 302 which is set to false. 302 is area of display.Created a BGL using SBX313 which is a street map to easily illustrate the problem. Typical photo BGL has same issue.Note that the underlying landclass is showing through the photoscenery. If I move the aircraft this same area moves with it exposing the landclass. The photo BGL is at the highest priority (top of list) in the Scenery Library editor. All Ultimate terrain and ORBX items turned off so that only default items are set to true in the scenery.cfg. The exception is area 302 which is also set to false.This is something I have never seen before after making many gb of photoscenery. ??

Hi there,check the Terrain SDK's section on Resample.exe regarding the LOD parameter. Looks like your maxLOD is set too low, which leads to this effect. Of course, your texture resolution slider section also influences this.Cheers, Holger

Right. SBX will use "LOD auto" which causes resample to compile LODs based on the source photo resolution. You need to edit the .inf file that SBX creates.for example, I create a quick SBX map from virtual earth @ zoom level 12 and compile it. SBX creates this inf for me:

[Source]   Type = BMP   Layer = Imagery   SourceDir = "."   SourceFile = "L12X2045X2051Y3157Y3161.BMP"   Variation = All   NullValue = 255,255,255   SamplingMethod = Gaussian   ulyMap =  38.0999826473649   ulxMap = -90.1318359375   xDim =  .000171661376953133   yDim =  .000135246129596434[Destination]   DestDir = "."   DestBaseFileName = "Photo01"   DestFileType = BGL   LOD = Auto   UseSourceDimensions = 1   CompressionQuality = 85

I look at the resulting Photo01.bgl in sdk TMFViewer, and see that LODs in the BGL are from 3-11. That's not good enough, as default terrain is LOD15. So I edit the LOD command:

[Source]   Type = BMP   Layer = Imagery   SourceDir = "."   SourceFile = "L12X2045X2051Y3157Y3161.BMP"   Variation = All   NullValue = 255,255,255   SamplingMethod = Gaussian   ulyMap =  38.0999826473649   ulxMap = -90.1318359375   xDim =  .000171661376953133   yDim =  .000135246129596434[Destination]   DestDir = "."   DestBaseFileName = "Photo01"   DestFileType = BGL   LOD = 3,15   UseSourceDimensions = 1   CompressionQuality = 85

Save the file (note found in SBX "Work" subfolder) and drag/drop onto resample (in "Tools" folder). Resample will rebuild your Photo01.bgl, this time creating LODs 3 through 15 and that will cover the default terrain tiles (confirm result by looking at file in TMFViewer).scott s..

Thanks - SBX LOD at 10 so will "adjust".
