Hey,
i created a landscape a few months ago and i can remember using a “preview” material on accident and i thought i had removed it. Still, i can see the preview-text on top of any other material or mesh.
Hope you can help me fix this, I´m really frustrated because I don´t know how.
Thanks!
This looks like the “lighting preview” debug decal being projected on the material in editor. Build your lighting and it should go away.
Thank you SO much! You are right, it is the Light Source, thanks 
Thank yout, it worked! I was so frustrated haha, thanks man!
Another way, if using baked lighting (static / stationary), is go to Project Settings > Rendering > Optimizations and disable “Render Unbuilt Preview Shadows in game”. The text can also be changed, and that’s somewhere in Project Settings or Preferences too.
