There's a bazillion road entries in that CIV4RouteModelInfos.XML file, and none of them reference dds files. How do I fix this?
Well, but you didn't change the information in the CIV4RouteModelInfos.xml.... you have to add new route model infos for each of the various directions... so you have to copy all route model info entries that have "ROUTE_ROAD" as their route type and then change this to ROUTE_TRAIL
Try CIV4SymbolMeshPaths.XML. There is an extra bit at the bottom that might be relevant.
Well, this might be totally off base, but the order in which you did it might matter. For instance, you have the trail before roads in one XML file, and after roads in that last one. In most cases it should not matter.
Did you try clearing the cache?
Unknown key "ROUTE_TRAIL" in blahblah.xml
Illegal XML value
Can you ZIP up all the files you've added and changed and upload them here? If so, we can run them ourselves. Perhaps you have a malformed XML file? It's surprising that cIV isn't reporting an XML error of some kind since those are the only changes you've made. (That's all I was saying above, that the game seems to be behaving poorly).
