extends VRTK_BaseHighlighter


Swaps the texture colour on the Renderers material for the given highlight colour.

Due to the way the object material is interacted with, changing the material colour will break Draw Call Batching in Unity whilst the object is highlighted. The Draw Call Batching will resume on the original material when the item is no longer highlighted.

Script Usage:

  • Place the VRTK_MaterialColorSwapHighlighter script on either:
    • The GameObject of the Interactable Object to highlight.
    • Any other scene GameObject and then link that GameObject to the Interactable Objects Object Highlighter parameter to denote use of the highlighter.
  • Ensure the Active parameter is checked.

Inspector Parameters

  • Emission Darken: The emission colour of the texture will be the highlight colour but this percent darker.
  • Custom Material: A custom material to use on the highlighted object.

VRTK/Examples/005_Controller_BasicObjectGrabbing demonstrates the solid highlighting on the green cube, red cube and flying saucer when the controller touches it.
