→What makes a good texture sheet?

The ideal texture sheet is a compromise between these two extremes - structured enough to de-emphasize landclass boundaries, not so structured as to lead to bad tiling. | The ideal texture sheet is a compromise between these two extremes - structured enough to de-emphasize landclass boundaries, not so structured as to lead to bad tiling. | ||
Another thing to consider when extracting a texture from aerial photography is that the land may be often dusty on the photograph. That is problematic because in FGs texturing scheme we want to be able to | Another thing to consider when extracting a texture from aerial photography is that the land may be often dusty on the photograph.

So you may have to work with an image processing software to adjust hue and contrast of a texture sheet after taking it from a photograph, and run a mapping algorithm to make sure it does not generate seams when repeated. | So you may have to work with an image processing software to adjust hue and contrast of a texture sheet after taking it from a photograph, and run a mapping algorithm to make sure it does not generate seams when repeated. | ||
