Hey. You can set these values here.
Please note that I used a Margin value of 40 px for better visual clarity.
Also, you cannot use a Border Margin value lower than 0 (zero) — in this case, the value is simply ignored.
In practice, there is no real benefit in doing what you are trying to achieve, because when the camera moves away from the object, the texture undergoes filtering and approximation. As a result, you will start seeing a different edge of the texture in places where you do not expect it.
This is exactly the reason why a sufficiently large margin is used.
The same applies to texture borders, because textures are effectively treated as infinitely tiled.
