I'm trying to experiment with alternative terrain textures for the scenery which I have built for the UK, but which looks odd when it's painted to look like an irrigated American prairie :�) I took a look at $FG_ROOT/materials.xml, which defines how the materials are put together, and determined that it was mixedcrop.rgb which looks like the prairie: <material> <name>MixedCropPastureCover</name> <texture>Terrain/mixedcrop.rgb</texture> <xsize>4000</xsize> <ysize>4000</ysize> ... the texture is an RLE encoded RGB file: /usr/local/FlightGear/data/Textures/Terrain/mixedcrop.rgb: SGI image data, RLE, 3-D, 256 x 256, 3 channels so I used the GIMP to make an alternative one: /usr/local/FlightGear/data/Textures/Terrain/UKMixedCrop.rgb: SGI image data, RLE, 3-D, 256 x 256, 3 channels
and altered the reference in materials.xml to try it out: (diff output): 1098c1098 < <texture>Terrain/mixedcrop.rgb</texture> --- > <texture>Terrain/UKMixedcrop.rgb</texture> However, FlightGear behaves very strangely with this configuration in place: large parts of the landscape are re-textured with different textures at seemingly random intervals (sea, grass, urban, but not UKMixedcrop). If I just overwrite mixedcrop.rgb with my file and leave materials.xml in its original state, I get the prairie back! How does it do that? Have I misunderstood the relationship between the scenery building and the rendering of the terrain at run time? I'd be grateful for a clue, and then I promise I'll write it up for the wiki !
