World To Object Node

The World To Object node transforms a position or direction specified on its Input from World Space to Object/Local space. This node will also return the current game object's pivot position if Input is left unconnected and its default internal value of (0,0,0,1) is used.

NOTE: When connecting a Vector 3 type data into Input, ASE will automatically cast it into a Vector4 type and set its w channel to 0, since it's the cast default behavior across all nodes.
This leads to incorrect results if that vector represents a position since the w channel value is important when doing a positional space transform. On these situations a new w channel with a value 1 should be appended to the original position vector via the Append node and its result should then be used on the World To Object node.


For the inverse Object To World transform please check the Object To World node.
