Z.GravityBillboard

Description

Section titled “Description”

A Z.GravityBillboard node is a group that will be automatically rotated so that its Z axis will point upwards, away from the direction of gravity in the real world. The node calculates the “minimum” rotation required - that is the axis of rotation will be calculated so that the amount of rotation to achieve this alignment is the smallest possible.

For example if you have a Z.GravityBillboard node underneath a target and the target is kept horizontal then the Z.GravityBillboard node will not result in any noticeable change in the rendering of any children of the node. However as the target is rotated away from horizontal then the effect of the node on the rendering of its children should be clearly visible.
