Background Image
Lets first prepare the background image for us to use.
In Photoshop, load up your image and adjust the colours
by using the Brightness/Contrast, Hue/Saturation and color balance.
Resize the image to your preferred output resolution, and keep a record of the image size.
Save, and load the image into Max, by opening your environment dialog box
and dragging the image into your environment map slot using the Asset Manager.
To be able to see the image in your max viewport, we need to load it into the viewport background,
bring up the viewport background dialog box, found under the Views menu.
Check Use environment background, and Display Background.
Now we can see the image in your perspective viewport.
