smoothing all of the terrain

Hi im looking to be able to smooth the whole of the terrain at once as i have used a height map and it has left the terrain almost pixelated if their are any editor scripts or anyway to create a very large brush id like to know

i have compressed the image of the height map quite a bit

Don’t think I’ve seen anything like that on the asset store. Have you checked the basic settings of the terrain are not distorting things? And can you not just manually smooth it using the built in smooth tool?

If it’s full of unexpected hard edges then it’s probably something wrong with your height map. You could always try applying a smoothing filter in photoshop.

I’m almost 100% positive, that this height map was used to create the desert map in PlayerUnkown’s Battlegrounds
