How do you add mountains in the background?

Questions & Answers

I understand you can add mountains to the skybox, but how do you add 2d planes with painted mountains on them AND have them render through the culling limit. I searched all over and resorted to asking here. Mountains created by the terrain disappear at a certain distance, so what are ways you can add mountain ranges?

Thank you in advance!

There are some good add-ons in the Unity assets store that you could use. 1

As for when you get too far the terrain disappears, you have to change the Clipping Plane - Far value in the Camera from the default 1000. It depends on how big your terrain is.
