Confirmed last month that a game engine upgrade was coming for Age of Wushu, Snail Game recently teased the in-development project with a couple of comparison images. The rumoured Unreal Engine 3 was nowhere to be found, which means it will be an upgrade on the in-house game engine.
The only external software listed is the Autodesk Beast, which is used to “realistic lighting in games”. Other than improved lightings and weather, objects such as clothing characters wear are more detailed with better physics when moving. The update is due on 8th August in China.
