There are a few things that I reference in the demo level you’ll want to add.
In the editor, click ‘Add New’ and then ‘Add or Content Pack’, and add :
- Starter Content - The sample landscape material I use references a few textures from there
- One of the character features (Third Person/First Person). The WorldManager just needs a reference to any pawn, I’ve used the ThirdPerson one in the demo videos.
- My demo level uses [Community Project] WIP Weather & Water Shader - Game Development - Epic Developer Community Forums for the water. If you want to use that you’ll need to include their plugin in your project as well
