How to make sure the bottom of the screen is on virtual ground

This is an excerpt from The Virtual Screen Section. Please check out the full article for more information on using the Snap Movement mode to align your camera to any surface you’d like.

Use the Floor For Larger Displays!

If your physical display is large enough to reach all the way to the floor, the best practice is to also root the ARFX camera to the virtual floor of your scene. There are two simple ways to do this:

While In-Play.

You use Snap Mode to have the camera set itself to what it thinks is the floor. Pressing T or Left Stick Button will enable Snap Mode and then tapping Down Arrow or DPad Down will cause the camera to snap to the floor using your screen’s height. Once you have a good position, create a bookmark (0 or DPad Left when not in Snap Mode) at that position to save it for use.

In Editor.

Simply move the camera itself and use the outline of your virtual screen as a reference point. Once you see that the solid line that makes up the screen turns into a dotted one, move it up one step, and it should now be aligned with the floor.

It may be hard to see depending on your display and resolution, but there should be a distinct different between the screen not clipping into the floor and when it is.  

Notice how the screen maintains contact with the floor as the image distorts. The effect in the physical camera’s viewpoint should make the illusion of looking deeper into the scene all the more realistic!

You can do this effect even on walls. Just align the sides of the screen to that of a way to get another interesting virtual shot.
