Orient Object to Surface
Re-orients an object to align to the nearest surface. This is typically used when placing objects on an uneven surface.

Child Face: Reference face on the child object.
Execute Per Array Element: If enabled, this placement rule will be applied to each element within the array, provided that the child object's source is an array.
In this example, multiple cars are placed on a ground object currently in the scene. The "Put Object" placement rule performs the initial placement of the car on the ground. It is then rotated about its Z axis by a random amount, and finally oriented to the surface using its bottom face.
