→Several materials may be defined in a single script. The script format is pseudo-C++, with sections delimited by curly braces ('{', '}'), and comments indicated by starting a line with '//' (note, no nested form comments allowed). The general format is shown below in the example below (note that to start with, we only consider fixed-function materials which don't use vertex or fragment programs, these are covered later):

→Example: ambient 0.0 0.8 0.0

→Another important factor is that material names must be unique throughout ALL scripts loaded by the system, since materials are always identified by name.

→Material scripts are loaded when resource groups are initialised: OGRE looks in all resource locations associated with the group (see Root::addResourceLocation) for files with the '.material' extension and parses them. If you want to parse files manually, use MaterialSerializer::parseScript.

→Material scripts offer you the ability to define complex materials in a script which can be reused easily. Whilst you could set up all materials for a scene in code using the methods of the Material and TextureLayer classes, in practice it's a bit unwieldy. Instead you can store material definitions in text files which can then be loaded whenever required.

→OGRE drives many of its features through scripts in order to make it easier to set up. The scripts are simply plain text files which can be edited in any standard text editor, and modiying them immediately takes effect on your OGRE-based applications, without any need to recompile. This makes prototyping a lot faster. Here are the items that OGRE lets you script:
