Can't add sculpting layers to landscape

I have a landscape from the marketplace and I’d like to modify it non-destructively. In the documentation (Landscape Edit Layers | Unreal Engine Documentation) I see that there is a “Layers” group where one can add layers. I don’t have that.

What am I missing?

Afaik, you have to enable layers upon creation. I don’t think you can do it later. Best way, imo, is to export height map, create new landscape with layers and import the hm.

It’s that pesky little checkbox “Enable Edit Layers”, the first setting in the “Landscape” section of the Details panel of a Landscape object. Check it, confirm, and the Sculpt tool will suddenly have an “Edit Layers” section.
