## Detailed Description

Class for managing Material settings for Ogre.

Materials control the eventual surface rendering properties of geometry. This class manages the library of materials, dealing with programmatic registrations and lookups, as well as loading predefined Material settings from scripts.

When loaded from a script, a Material is in an 'unloaded' state and only stores the settings required. It does not at that stage load any textures. This is because the material settings may be loaded 'en masse' from bulk material script files, but only a subset will actually be required.

Because this is a subclass of ResourceManager, any files loaded will be searched for in any path or archive added to the resource paths/archives. See ResourceManager for details.

For a definition of the material script format, see Material Scripts.

Ogre comes configured with a set of defaults for newly created materials. If you wish to have a different set of defaults, simply call getDefaultSettings() and change the returned Material's settings. All materials created from then on will be configured with the new defaults you have specified.

|  | const NameValuePairList * | createParams = 0 )

Create a new material.

## getByName()

MaterialPtr Ogre::MaterialManager::getByName | ( | const String & | name,
|  | const String & | groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME ) const

  ResourceManager::getResourceByName

References Ogre::ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME.

## getDefaultMaterial()

MaterialPtr Ogre::MaterialManager::getDefaultMaterial | ( | bool | useLighting = true | ) |

Parameters

  useLighting | whether the material should be lit

## initialise()

## setDefaultTextureFiltering() [1/3]

virtual void Ogre::MaterialManager::setDefaultTextureFiltering | ( | TextureFilterOptions | fo | ) |

virtual

Sets the default texture filtering to be used for loaded textures, for when textures are loaded automatically (e.g.

by Material class) or when 'load' is called with the default parameters by the application.

Note
  The default value is TFO_BILINEAR.

## setDefaultTextureFiltering() [2/3]

virtual void Ogre::MaterialManager::setDefaultTextureFiltering | ( | FilterType | ftype,
|  | FilterOptions | opts )

virtual

Sets the default texture filtering to be used for loaded textures, for when textures are loaded automatically (e.g.
