I recently found some tutorials on photorealistic scenery design, and thought I'd give it a go. I decided to start with a small airport (Eindhoven Airport, EHEH), since it has just one runway and not too many taxiways. I got as far as creating a water and blend mask (even though the water mask is useless 'cause I decided to cut out the water in the blendmask..). Then I made the INF file, dropped that into resample.exe and it started working. However, when I copy the .bgl file to my scenery folder and add the area in P3D, it'll show all the photoreal scenery (as in, the full square I selected in SBuilderX), in stead of the parts of the image I left white. I've gone over the tutorial a few times, and I'm pretty sure I'm doing the right thing. What am I doing wrong? My INF file is as follows: Spoiler: INF file [Source] Type = MultiSource NumberOfSources = 2 [Source1] Type = BMP Layer = Imagery SourceDir = "." SourceFile = "EHEH-PH1.BMP" Variation = All ulyMap = 51.4651303853649 ulxMap = 5.35446166992187 xDim = 5.36441802978496E-06 yDim = 3.34307973233591E-06 Channel_BlendMask = 2.0 [Source2] Type = BMP Layer = None SourceDir = "."

Where am I going wrong?
