I have an earth file that brings in elevation data through a GDAL plugin. If I set a heightfield cache and run the application, I see elevation on the globe, and I see files being generated in the cache directory. If I then rerun the application in offline mode, I don't see any elevation data at all on the globe. Is there an issue with heightfield caching, or (more likely) have I missed something? I can't recall which rev I took from the repository, but it was probably a couple weeks ago. Thanks for your help!
