I realize this is a driver bug and not osg related, still I post this in
hope this knowledge saves someone's precious time wondering why VTF
makes things acting very weird.
For courageos ones venturing into ati glsl wonderland, this is what I
have discovered. The unifrom name of the "baseTexture" from
osgshaderterrain must be alphabetically before the "terrainTexture", as
it is by default. So for example renaming the heightmap to
"aterrainTexture" render the object white, while "cterrainTexture" works
just fine.
