Anyone having problems with UV orientation affecting aiFlakes in Arnold5?

I have run into a problem with aiFlakes in Arnold 5 in Maya. When using aiFlakes in any mode (UV, Object, etc). The orientation of UVs drastically changes the way the surface looks. This means if two objects (like two car doors) have different UV orientation, it creates a weird look. Also, if an object rotates in space, the intensity of its specular reflection would change. Here's an example:

I am setting up my network following this example:

I have tried several other methods like using the aiNormalMap node instead of bump2d, but this problem persists. Has anyone else encountered this?
