Hi! So, got a little asset test projekt going, started with UE 4.12.5 and everything was fine. 
Then i switched to UE 4.13, and now every new asset i put in got a problem with the textures. 
Roughness and gloss works fine, but Normal is not effecting anything and the Albedo is, well, off.
Texture on flat plane looks normal though. 
When i put the same Mat on a different asset, its working as expected.
As i said, in UE 4.12.5 its working, so there must be a change i do not see. Not in the import settings though, i checked that already.
Look at attached images for ref. 
Hope someone can help me out! 
Greetings, Hirudo

I compared the import-settings, no problem there. So like Mr. Holmes said, its a problem Epic has to fix unfortunately...
