Create boundaries around landscapes?

Hello, I’m trying to find out the best way to create boundaries/invisible walls around a landscape.

For example, I have a water body here, I’d like to create a collision around the border of the water so the character doesn’t walk through the water.

Another example here. My level has hills, the player can walk though them and go out of boundaries. How can I prevent him from doing that? I could ad invisible cubes around but that would take too much time and there is probably a better way. Any help would be appreciated. Thank you.

Blocking volumes would be the usual way. It’s not procedural, but you can make the volume any shape ( it’s a brush ):



Thank you! This will do :slight_smile:

Great, please mark the answer as correct, if you think it will help others :slight_smile:
