Game: Train Sim World 2 (
steam page)
UE4 version: 4.26 (current version) / 4.23+ (previous versions)
All works fine - including meshes, textures and animations - with the latest umodel build (1377 at the moment). Though the game is using custom materials for trains, and also most of trains' animations are additive.
Update: Latest game version is using 4.26, all still works fine with latest umodel build (tested with 1562). Note that UE version can be different for different stores, like EGS or steam.
