## Member Function Documentation

virtual bool Ogre::RenderQueue::RenderableListener::renderableQueued | ( | Renderable * | rend,
|  | uint8 | groupID,
|  | ushort | priority,
|  | Technique ** | ppTech |
| ) |  |  | `[pure virtual]`

Method called when a Renderable is added to the queue.

Remarks:
  You can use this event hook to alter the Technique used to render a Renderable as the item is added to the queue. This is a low-level way to override the material settings for a given Renderable on the fly.

Parameters:

  | rend | The Renderable being added to the queue
  | groupID | The render queue group this Renderable is being added to
  | priority | The priority the Renderable has been given
  | ppTech | A pointer to the pointer to the Technique that is intended to be used; you can alter this to an alternate Technique if you so wish (the Technique doesn't have to be from the same Material either).

Returns:
  true to allow the Renderable to be added to the queue, false if you want to prevent it being added
