The material Engine/EditorShapes/Materials/M_ShapeMaster.M_ShapeMaster is missing two textures:
/Engine/EditorShapes/Textures/T_ShapeNormal.T_ShapeNormal /Engine/EditorShapes/Textures/T_ShapeDiffuse.T_ShapeDiffuse
RESULTS:
Both Texture Sample nodes show errors because of missing textures.
EXPECTED:
The Texture Sample nodes properly show the textures being used.
