Texture appearing in squares across the map I was following a tutorial on how to paint textures on to a object and for some reason, when I started painting, the texture didn't show up in its proper place. It just appeared in squares all around the map. if anyone has a solution to this, Please let me know.
I would start by looking at your UV map. If you try using the color grid or UV preset textures (when you create a new texture) you should be able to see if your UV map makes sense, or if it's causing the issue.

If the UV map is the problem, you can probably just UV unwrap your object again. To make a flat UV map from above your object (which should work for your terrain), switch to edit mode with Tab, toggle to orthographic view with Ctrl+5, switch to top view with Ctrl+7,  then select UV unwrap (or press U) > Project from View (Bounds).
