Priority: 2Necessary for shipping a final release

-

Severity: 3Workaround is possible

Steps to repro:

1. Open attached project and 't1' scene;
2. Observe terrain's rendering.

Expected result:
Terrain is rendered with zero smoothness value.

Actual result:
Terrain is rendered completely specular (with maximum smoothness value). See attached video and screenshots.

Regression introduced in Unity 5.6.0b3.

Workaround is to use textures with .jpg, .tif or .psd format as terrain's basemap.
