In this mini-tutorial, we'll cover setting up displacement for Megascans surfaces in UE4.
First, ensure that you've checked the Displacement map in both your Download and Export Settings within Bridge or the Megascans website.
Click the Megascans icon at the top of the UI in Unreal Engine to open the Megascans plugin and make sure "Enable Displacement" it checked, then export your maps from Bridge.
The exported asset will appear in UE4.XX as shown below. Notice that the Livelink has created a Megascans folder and subfolders. This is where your assets will be imported to.
Drag the material instance into the viewport and onto the plane and you'll get the following result.
Now let us set up the displacement as well. Taking a closer look confirms that height data is not visible. It is just the normal map that gives the illusion of it.
Since we had already enabled Displacement in the Livelink its map will be imported and setup accordingly. But, it will be disabled by default so we'll have to enable it manually.
Open the Material Editor of the imported asset. Ensure to check the Params button to show all attributes in the Editor window. Ensure that the Displacement attribute is checked.
Now scroll down to the Tessellation section and you will notice that all the attributes will be unchecked.
Enable the Near and Far Tessellation by an equal, but nominal, amount. Then increase the Displacement Height to incorporate displacement.
- The corresponding result is shown below.
