Hi @UberPz,
Hmm yeah, something is definitely up with your normal map. It’s clearly not adding the stone normal texture along with the general issues you’re seeing.
Immediately, I see that your static switch parameter “Use Normal Map” is set to false by default. Try checking that box to set it to true by default.
If this does not solve your issue, make sure your normal map is set up correctly. Where did you get it from? If you made this yourself, did you export it for OpenGL instead of DirectX?
If your normal map is set for OpenGL, you’ll need to check this button:
Also, make sure your normal map is using the correct compression settings.
Likely though, I think the first suggestion will solve your issue 
Let me know how that goes!
