Landscape layer blending

I would like to know if its even possible to do something like this; with the landscape layer blending automatically somehow. I really really dislike the 1-0 blending which really don’t work for any kind of landscape because there are either rocky ground or there is no rocky ground at all… The fade which is there looks to strange to be used in a realistic setting…

Here is what I get when I use an 8k BW flowmap from world machine to mask between the layers; but you still obviously get the same blending. I can change the contrast of the map to make it very sharp but I would like to use a grunge texture as the blending…

Here is an article another guy gave me but I am not that great at math and coding to implement anything like that; Advanced Terrain Texture Splatting

You do it on landscapes like you do this in a normal material with a heightmap.

what height map do you use? I see that you have a height blend option in the layer blend. But what kind of heightmap are we talking about, the landscape heightmap or do I make an heightmap based upon an alpha?

Edit I tried a random BW with that node and it worked. But why can you use a heightmap for that? Should just use a normal alpha map which I create? Confusing naming…

You have to use a heightmap based on the texture you want to use. A heightmap is sort of an alpha map, it just tells the system what parts of the texture are elevated and which are not. Just read about it ^^

No I understand what a height map is, I am using that for the landscape itself. And I figured out how to kind of do it. But what I don’t understand is how to properly use it, there seem to be no good example and the landscape expression documentation really don’t go in depth about it. Should the texture be a gradient from one side to the other or just a tileable alpha map? Does this look alright?

If there is an example on how these images actually should look like I would be grateful to look.

This is what it looks like now;

It seem to still fade between, and the texture map have no fade on it and is just a tileable one… Is there a setting or something where I can fix that?
