List of all members.

## Public Member Functions
virtual | ~Listener ()
virtual void | notifyMaterialSetup (uint32 pass_id, MaterialPtr &mat)
| Notification of when a render target operation involving a material (like rendering a quad) is compiled, so that miscelleneous parameters that are different per Compositor instance can be set up.
virtual void | notifyMaterialRender (uint32 pass_id, MaterialPtr &mat)
| Notification before a render target operation involving a material (like rendering a quad), so that material parameters can be varied.

## Member Function Documentation

virtual void Ogre::CompositorInstance::Listener::notifyMaterialRender | ( | uint32 | pass_id,
|  | MaterialPtr & | mat
| ) | `[virtual]`

  | Notification before a render target operation involving a material (like rendering a quad), so that material parameters can be varied. Parameters:
  | pass_id | Pass identifier within Compositor instance, this is speficied by the user by CompositionPass::setIdentifier().
  | mat | Material, this may be changed at will and will only affect the current instance of the Compositor, not the global material it was cloned from.
