is their a way to smooth entire map without having to do so manually?

I want to smooth my enture map, but due to the size of map. I would love to just have an option to smooth all. is this possible?

can someone please tell me if this is possible.

Are you talking about terrain here? Or some other kind of maps?

I dont think it is possible currently. You’ll have to increase the brush size to the highest value and smooth like that.

Ah I thought as much, this would be a nice effect to the engine to be honest, anyway thank you for replying.

You could in fact export the heightmap, apply a blur to it in Photoshop, then import it back again. Can be tricky due to lack of immediate feedback of course, but it is doable.
