                                -------------------------------------- INFLUENCE INDICATION SCRIPT ------------------------------------------

- SUMMARY: This script references 4 GameObjects in the scene (4 shapes of influence) and sets each active or inactive according to the brush being used
- USED IN: (MeshInteractor.cs) Called in Update() with SH_BrushShape category of functions.
- FOUND ON: 'InfluenceIndication' Game Object in Unity. GameObjects it references are attached to 'Right Hand' on 'VR Origin'
