parseMaterialIndices method

dynamic parseMaterialIndices(Map MaterialNode)

Implementation

			"mappingType": 'AllSame',
			"referenceType": referenceType
		};

	}

	var materialIndexBuffer = MaterialNode["Materials"]["a"];

	// Since materials are stored as indices, there's a bit of a mismatch between FBX and what
	// we expect.So we create an intermediate buffer that points to the index in the buffer,
	// for conforming with the other functions we've written for other data.
	var materialIndices = [];

	for ( var i = 0; i < materialIndexBuffer.length; ++ i ) {
