Trying to create Landscape Blend Layer but its still blank

Hey! im trying to create a new landscape blend layer and no matter what kind of textures im chosing its still blank… i remembered its worked for me before and in youtube i saw video which they did same thing like this.

what can i do ?

That’s normal.
Go to the landscape paint and you will see the layer materials on the left, you then have to press + to add a layer, then it will ask where to save the layer.

Save layer where your material is.

You must do this for each layer.

Then select the layer you want to paint with, and start painting.

The first paint that goes on the black, is generally square.

Then when you paint over the other layers, it matches you paint brush.
