Description

If a user enables 'Crack Free Displacement' when using tessellation on landscapes, the displacement becomes flattened. This does not occur on regular static meshes, and seems to be tied only to landscapes.

Regression?

Steps to Reproduce

1. Download and Open Attached project.
2. Open the M_Displacement material
3. Check 'Crack Free Displacement'

Expected The option tries to remove cracks caused by displacing the VertexNormalWS, and maintains the displacement.
