Any material that already exists in 4.11p1, with tessellation enabled, causes assigned geometry to disappear. Any material created within 4.11p1, with tessellation enabled and a base color, causes the material preview to be blank.

Checked in 4.10 4.11 and 4.12

Does not occur in 4.10 or 4.12

Steps to Reproduce

1 ) Launch 4.11p1

2 ) Create a blank BluePrint project with starter content

3 ) Edit the M_Chair starter content to enable tessellation and save -> no shader error message, but the chair doesn't render.

4) Create a new material, give it a visible base color and save, then enable tessellation and save -> no shader error messge, but the material preview is blank

Expected : Visible tessellation on chair. Result : Fully Transparent Geometry

Expected : Material Preview available. Result : Blank Material Preview
