-    Summary:
-    A slice containing the LandscapeCanvas component can be created/instantiated.
-
-    Expected Result:
-    Slice is created/processed/instantiated successfully and free of errors/warnings.
-
-    Test Steps:
-     1) Open a simple level
-     2) Create a new entity with a Landscape Canvas component
-     3) Create a slice of the new entity
-     4) Instantiate a new copy of the slice
