Texture rectangle is out of bounds? (689 + 5 > 512)?

This might be a very simple question, my project is only an environment, yet I can no longer texture the terrain. I am getting errors like

Texture rectangle is out of bounds? (689 + 5 > 512)?
Texture rectangle is out of bounds? (857+ 5 > 512)?

does anyone have an idea?

Your UV mapping on your objects is clearly going outside the 1,1 scale somewhere :wink:

How would I got about fixing that? I’m just an environmental artist for this project :confused:

Uh you are environment artist and don’t know how to map UVs?
What software do you use?
