This Unreal Engine 5.4 video is about updating Kenney’s Tower Defense Kit to the newer version.
We start by removing the old assets we never needed to import in the first place, and then re-import the updated versions. We then go through and replace uses of the old busted, with the new hotness, and then show how everything is working flawlessly.
