Weird moire-ish normal map
Here's what I did:
Modelled the high res mailbox and used the surface sampler to create a normal map.
I created a new Blinn and a new 2dplacedtexture file and pointed it to my normal_map.tga file, then used the connection editor to map OutColor to NormalCamera.
I turn on High Quality Rendering, hit 6, and this is what I get.
The details like the rivets and the rounded edges I added with photoshop. These details are much glossier (note, no spec map added yet) than what was generated from the get-go by Maya.
I have a ho-hom PC with a Quadro 750 using both the most recent version of drivers as well as the last certified version on the Maya qual charts. I have deleted my Maya folder and let maya recreate it. I have reset all the defaults on my video settings.
Even more frustrating is that it does it as well on my work PC, which is a GeForce 6800, but not a friends PC who is an environment artist.
