How to find an Named DCS/DOF node from a vgObject

 

Vega Code Example

 

 

 

 

 

 
 

This example function illustrates how to fined a named Performer  Dynamic Coordinate System (DCS) pfDCS node that is part of the given vgObject.

 

Note that the pfFindNode function is case sensitive.

 

Also you should be aware that if the vgObject is an OpenFlight file and the node uses the default name; such as dof1 and has not had its position  altered, then the node might get removed during the flatten and clean process done by default after the file is loaded.

 

It is good practice to name all Dof/Lod/Switch nodes or any  node of importance, this practice will save you time when debugging
