You can look up "texture coordinates" from other resources such as your favorite search engine, or graphics tutorials. You can look up "texture coordinates" from other resources such as your favorite search engine, or graphics tutorials.
Tip: map your UV coordinates to widgets (using `SliderFloat2` or `DragFloat2`) so you can manipulate them in real-time and better understand the meaning of those values.
If you want to display the same image but scaled, keep the same UV coordinates but alter the Size: If you want to display the same image but scaled, keep the same UV coordinates but alter the Size:
