How to use Materials with Landscapres

I notice in Unreal Engine 4.13 and up, when trying to use “Materials” that will be used with landscapes, you would normally have to open a newly created Material, then within the “Material Editor” you would go to “Usage” section within the “Details” panel and Click the check-box for “Used with Landscape”. I notice that parameter is gone. This affects me as I can’t select “Materials” listed below “Target Layers” when I am using the “Paint” Tab for Landscapes. What is the work-around for that? I have an attachment listed that illustrates the parameter that is exactly missing. Can anyone give me a solution. If so thank you. - Normdiggy
