Hey there - a rather small thing.  
  
  
  
  
  
the following description is wrong:  
  
  
  
  
  
 /_!_  
  
   
**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; @Function&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GetTransformationMatrix**  
  
   
**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; @Output&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;mOut&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Transformation matrix**  
  
   
**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; @Input&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;node&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Node to get the transformation matrix from**  
  
   
**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; @Description&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Generates the world matrix for the given Mesh Instance;**  
  
   
**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;applies the parent’s transform too. Uses animation data.**  
  
   
**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;** \*\*\*/  
  
  
  
  
  
the function returns the local transformation matrix - it doesn’t apply the parents transform. there’s another function for the worldMatrix.
