the TextureChunk has a priority field which allows you to reduce the
priority of textures (reduce, because the default value is 1.f which is
highest priority). So you could give a different, smaller value to all
other textures or you could modify the TextureChunk prototype object
right after osgInit (i.e. before any textures are created) and lower the
default priority and just set it to 1.f for the important textures.
You can get the prototype like this:
TextureChunkPtr tcProto =
TextureChunkPtr::dcast(TextureChunk::getClassType().getPrototype());
Cheers,
Carsten
