I want to learn how to do the gradually revealing of scene as you walk forward but I don't know the name to search for it.

Thanks

also- Is the OK button after choosing the tag not working? (I had to press enter)

    Isn't the scene just getting clipped by the far plane of the camera?
    Try changing the far and near values of the camera to see if that's the affect you are going for.

        Oh is that all. Sorry noob question but Does it do anything in term of optimization? Should I to learn the chunk system or LOD?
        I haven't start anything yet but I want to know best way to start making and optimizing mid sized scene like this.

            I'm not sure if it affects performance and I don't really know how godot does stuff under the hood.

            For my own game, I'm thinking of using a clipmap for nearby terrain and having a second camera with a miniature version of the terrain for stuff that is far away. I might do chunking for stuff like buildings, trees, and NPCs.

                I plan to do something like Silent Hill. I guess it is a chunk system with camera clipping. *btw I might have to learn Clipmapping too, so thanks for that.

                  I believe that's a form of frustrum culling but as others have pointed out Godot has build in LOD settings that can likely do a similar effect.
