Hi, I have made my own Texture Atlas in Photoshop and now want to use it on gameobjects. I know the height and width of each as well as the x and y positions of the starting points of each individual image. How do I tell Unity which objects should show each part of the atlas? Thanks!

You should be able to find many tutorials for UV mapping, regardless of what 3D package you use.
