DWORD length	// Length from 'MTRL' or 'MTNF'; 16+(16*count)+(4*parmcount)

	DWORD IsVideoSurface	// boolean
	DWORD IsPaintingSurface //
	DWORD 'MTNF' or 'MTRL'	// Used if the internal list of resource keys is non-null.
				// Note that it may still just be of zero length.
                               // TODO: Is 'MTNF' even used anymore?  Will using it case problems in TS4?

DataType TypeCode Size(in DWORDs) Data Description 1 1 Float 1 2 Vector2 1 3 Vector3 1 4 Vector4 2 1 Int 2 * Int[] 4 4 Texture A resource key index. In most cases it is a RCOL reference, however in the case of GEOM, it is a Key Table index. This data is padded to 16 bytes with 00. 4 5 TextureKey ResourceKey(in ITG order) padded to 20 bytes with 00

Notes

1. Valid texture reference types include { TXTC, DDS, ANIM } resource types.
