Tiled Normal Maps and rotated uv's.

So i always thought this was a doable thing? It looks like the tangents go a little nuts when i rotate my uv's even though it's a flat plane? 



I could understand if the grooves weren't lining up. and the bump was off there, but the whole polygon shading has be a little baffled. 



I think i've tried everything, left handed, right handed vertex normal method changed to unweighted. All hard edges and All soft edges. 

These are being tested in unity and maya 2016 simultaneously with the exact same results.

This just seems all kinds of efffed up. 

2016 and 2017 maya.

I don't understand the setup. Last pic looks like the vertex normals are screwy. But what's going on in the top pic?

You can rotate the polygons themselves but not the UV's.
Go into your texture node and change the color space from sRGB to Raw.

Okay so it's definitely the RAW thing. The problem was nothing was updating for me when i would switch it to raw. But then for some reason when i click on the icon for mat it would update. I don't think i've ever clicked on the mat icon in the attribute editor but somehow that fixed the basic shading thing with raw/srgb. I guess i should set up the auto color space selector now moving forward. 




Is it a better practice to run your details along the x or y access when it comes to doing things like borders on something like a floor? 

like in this:

Also huge thanks you two.

On newer games it shouldn't matter, but in the unlikely event you are making something for an older title or otherwise forced to use dxt1, then it matters.
