Making terrain texture fade into other texture?

Hello :slight_smile:

I am using the terrain tool, and I’ve made 3 different layers. I have a base texture on the terrain, and when I paint with another texture, the transition is very rough. It does not fade into the other texture at all. I want it to fade together with a 50% opacity on both textures.

I can see a “brush falloff” in the terrain paint brush settings, but it does not seem to do anything. Do I need to do something on the terrain material?
