I have tested these modifications to the master branch and in order for the
photos to be shown in the terrain, the shadder effect (inside the Rendering
Options menu) needs to be set to Performance (0); Otherwise the regular
terrain materials will show.

I believe that this patch is a great addition to the Scenery development as
it brings us closer to what you will most likely see when flying over that
region, and I do second Peter's request for most savvy and expert members to
add this change as a part of the master branch.

Subject: [Flightgear-devel] Photo scenery patch: request for help

This is a request for help to see if his patch could be put into flightgear.
I do not understand enough of flightgear to be able to push this forward
myself. My only involvement in all this are some scenery images I made that
use his patch (http://fgphotoscenery.square7.ch,
http://www.flightgear.org/forums/viewtopic.php?f=5&t=15174).

On my machine at least, also some modification of terrain-default.eff is
necessary, because when using Benoit's patch as he made it, the standard
texture is covering the photo texture except for very small regions like
streets and just around airports. This is due to the fact that
terrain-default.eff has evolved since Benoit made that patch of course.
Because I don't know enough about the shaders, I only could make a very
violent modification to terrain-default.eff that would allow me to see the
photo texture on top. This modification does break a lot of the shading as
Vivian and Frederic immediately pointed out.

The request for help therefore also includes to have a look at what needs to
be modified in terrain-default.eff in order to show the photo texture
without breaking all the rest.
