Hi - I asked this in response regarding a method to prepare a tpk for offline use: How does esri create the 'overzoom' effect for the world topo map service? Clearly the large scales say past 1:564 are drawing at the same resolution, but I can't figure out how to do that with my own caches. I thought it would be as simple as copying my largest bundle's LOD into the even larger levels, but that doesn't work.
Does the cache have to be exploded? Does it matter if the tile format is PNG vs JPEG? Any suggestions?
