Rhino - Tessellation - 'Crack Free Displacement' not compatible with meshes

Rhino - Tessellation - 'Crack Free Displacement' not compatible with meshes

Developer Notes

Adjacency buffer needs to be enabled in the static mesh build settings. It's not enabled by default if the imported materials don't require it.

Description

Meshes imported from rhino are not compatible with 'Crack Free Displacement'

Steps to Reproduce
  1. Import a Rhino .3dm file (One is attached)
  2. Open Master Material
  3. Set Tessellation mode to Flat
  4. Enable 'Crack Free Displacement'

Result: Materials with Crack Free Displacement enabled will show only default grid material on meshes imported from Rhino
