Displacement

The in-editor geometry tools have a displacement tool:

Mesh Displacement

• The Displace tool has been improved with multiple additions.
  • PN Triangle Subdivision - The PN Subdivision defines a smoother version of the mesh replacing each flat triangle with a curved mesh.
  • New Tessellation algorithm - A new mesh tessellation method has been implemented that improves the speed and granularity of both Uniform and PN triangle tessellation. The result is much closer to the tessellation shader.
  • Channel selection when displacing a texture map.
  • Scale and tile 2D textures.
  • Adjust intensity with a contrast curve.

Also, you can reimport a mesh with one click.

The question is what Epic has to say. Does anyone know the official position.

Hardware Tessellation Support

Article written by Jon C. Frequently we receive questions about UE’s support of (cross platform) hardware tessellation and our future plans for supporting it. Historically, UE has supported hardware tessellation for certain RHIs, however there are platforms, particularly consoles, that never received UE support for hardware tessellation. The reasoning behind this decision is that tessellation for any RHI requires regular maintenance, especially when optimizing for performance. In particular, o…
