Hello, all of a sudden, my normal maps and specular both are not showing in Unity. Any ideas onto why?
Some more information would be appreciated. I can say that I have had my materials disconnect themselves before. Sometimes this occurs when there’s a change to the project folders outside of unity. That’s about all I can guess without more information though.
What other info wold you need? 
i’m not sure if this can be, but may be you have your normal map meshes set up as static ?. hm?
Nope. they are not static.
Do you have lights in the scene? Do they work in a new project?
Please provide more info. Your first post right now can be summed up as “something is wrong somehow, please help”.
I have lights in my scene. Idk about them working in a new project yet.
Did you change the renderer quality settings for either the editor or the game view?
Yes. Maybe I should reset them?
Whats your current editor quality settings? if its set extremely low, this would explain why you would loose so many details. Put it back up to higher settings.
All are defaults. Editor : Good.
do you notice a difference if you change the shader from bump specular to diffuse?, sometimes the normalmap texture is not enough strong to mark relieve…
I was having a similar problem, but not sure if it is the same one you are having. I had imported and viewed a number of models with normal maps over a period of time without problems, but suddenly one, for whatever reason was imported differently than the others.
After trying a few things I noticed this error message: "shader wants tangents but the mesh (my mesh name here) doesn’t have them.
I selected the mesh in the import options checked “Calculate Tangents” and reimported. After that the normal maps showed up… well, normally.

Did you bake beast lightmaps inbetween?
I’m not sure if this will help, but I also had a similar issue. I found it actually related to my lighting system. While I still had my lights, all of them had been turn to “not important” rather than “important” or “auto.” This disabled all normal maps in the project. All of my textures were connected correctly, but the normal maps were not being rendered. By turning one of the lights back to “Important,” the normal maps showed up when that light struck them. Good luck!
