How to simulate continuation in a map?

I have a large map but of course it ends at some point. How can I make it so that the map does not end sharply, but instead there is a feel of continuation. I see two different situations:

1- You approach the end of the map and the ground just ends sharply. I thought of adding some boundaries before the map ends, but then I reduce the map size, which I want to avoid. Also maybe foliage could cover the end of the map?

2- You are anywhere in the map, look at the horizon and you should not just see sky, but some mountains. I thought of going to google earth and getting into street view and screenshot the far away landscape, then use that as a billboard to place at the end of the map.

Is there a better way to do it?

Distance meshes :slight_smile:

Things like mountain meshes which look quite awful if you’re near them, but look great in the distance. These are great

You can also use an HRDI

There’s a plugin for using them in the engine

Nice, but maybe to have a whole mesh for background is an overkill? How about billboards with mountain images? Then I guess the problem would be how to apply dynamic lightning to the mountain?

Anyway, if I use a mountain mesh, I guess it would be very few triangles and very bad textures right?

And this thing of HDRI, it’s like a skybox? The ones I’ve seen are not from far away mountains, but rather very close up ones. Furthermore, I would like to create a custom continuation of my map, since it is a real world location, that’s why I was mentioning taking screenshots from google earth street view.
