The X-axis value adjusts the fence to the left/right of the parent item, the Y-axis
value serves to move it fore/aft and the Z-axis value moves the fence up or down.
You may input the desired values directly from the keyboard by using the mouse
wheel.
RENDER TO DEPTH BUFFER ONLY-
This setting determines whether the to render the object only to the depth buffer.
Selecting ‘Yes’ allows the objects to cover items behind them on the scene but
allows the PhotoField and sky to be drawn over them.
For example, you could use this to place an “invisible” object into a PhotoField
airport that coincides with the location of an object in the PhotoField background.
You would then be able to collide with the PhotoField object. This also allows you
to fly behind the object and allows the object to cast shadows. The van placed in the
Sod Farm airport is a good demonstration of this feature.
To select whether an object will render to the depth buffer only, click on the
respective value. Use either the Up/down arrow keys on the keyboard or click with
the mouse to select the desired option.
RENDER DEPTH BUFFER ONLY (INHERITED)-
This value is non-adjustable. It is determined by the Render to Depth Buffer value
associated with folders above the current folder or object. For example, if a shack
has this property set to ‘Yes’ than the folder above the shack or any folder above that
folder has the Render to Depth Buffer Only property (described above) set to ‘Yes’.
