Painting Heightmap Landscape Materials?

Hi,

I’m following this document to paint my landscape. https://docs.unrealengine.com/latest/INT/Engine/Landscape/QuickStart/5/index.html

My question is, is it possible to paint the landscape and apply displacement map at the same time?

For example, I want to use height map to make the stones really come out. In my shader, I already have the height map but it doesn’t work. Maybe the landscape’s resolution is not high enough? If that is true, how do I fix it?

Height map in materials is only a mask to occlude other layers on the terrain- it is not a displacement/tesselation map.

As said above, the height map as you are using it is for the blending of layers.
I recommend you to not use displacement mapping for terrain it’s very very expensive and kills the performance. Look into POM.
