Wouldn't that color the whole box instead of making a gradient-like effect depending on how close the 'camera' is?
yea but thats the simplest way, you would only do it to very far out boxes anyways so i don't think it would be noticeable. having the effect applied to close ones would look ugly tho, but im assuming you just want it so that you have draw distance with a smooth buffer instead of boxes popping in when you hide/unhide them.
