I agree with on that it is strange however Barber Motorsport Park started working fine and Magny-Cours was the same issue as Silverstone and that started working too by putting in the file in the folder as a workaround. Could it be I re-downloaded the track pack had something to do with it?Humm. Interesting. Ok thanks for this information.
But the sampleTerrainpainting.dds file for Silverstone is packed into the spring.mas and summer.mas files.
The terrainpaint creates dry grass/dirt effects as well as shadow mapping. This file is track specific. So the Thruxton version will look strange when applied to Silverstone and vice versa.
Again I am not sure why you are having troubles you should have all the files needed to load Silverstone.
