Steps to reproduce:

1. Open user attached project
2. Open "BundleView" scene
3. Enter PlayMode and observe both Cylinders look the same
4. In Hierarchy find Loader -> TestScene and inspect "AlbedoNormal"
5. See that the material has a normal map attached to it
6. Under Shader select the same shader that's already set i.e. XPI/Standard to refresh the shader.
7. Normal map appears to function

Expected outcome: The right cylinder has a normal Map attached that functions properly
Actual outcome: The right cylinder has a normal Map attached, but it is not visible entirely

Reproduced on 5.6.1f1, 5.6.0f3, 2017.1.0b4

Notes: Couldn't test for regression cause project depends on MaterialEditor class methods that were introduced in 5.6.x
Project crashes while loading on 5.5.3p1 and lower. Delete Libraries folder to prevent that.
