As it turned out I wanted to trace my driveway using colors from the Paint program. So apparently all you have to do is add even 1 pixel of a color and it becomes a "color" photo.
Photoscenery maker worked pretty well. Actually took an area(about 3/4 mile) of aerial photo and placed it exactly where it's supposed to go.
My own residence was in the photo as a reference.
However, even though i used very precise Lat/Long coords, when I fly over the area,
the aerial photo texture is surrounded by large square of blue, which sure looks like water texture(light blue)
I ran PSM several times and made sure i did processes one at a time and left out the "merge Alpha texture' part, thinkin the sim thinks there's supposed to be water there.
Don't know if it means anything, but so happens, i had traced all of the roads in the aerial with a light blue color, almost, (if not the same as) the water texture color.
The "light blue" roads end at all 4 sides of the aerial photo.
Anybody have any ideas about getting rid of the light blue border? It's possible that my photo uses an area which is smaller than a standard "scenery cell" or something.
