Terrain blending issue

Hello there, one fast question about the terrain blending.

For example I want to blend sand texture with some stones textures. I’m using LB Height Blend and it comes like this :

albedo-s are just black and gray so I can see the blend

So I want to make it something like this:

I should put some adjustment after the blending, but I can’t figure it out how :slight_smile:

Best regards,
Sergey
