Statistics グループでは、有用なレンダリングプロセスのStatisticsの出力を制御します。ファイルはイメージの一部として(TIFFのみ)、あるいは個別のファイルとして保存できます。
Statisticsは、問題の特定やピンポイントなパフォーマンスの計測に有効です。 詳細はDetailed Statisticsを参照して下さい。

Report Rendering Statistics

オンにするとログを出力します。デフォルトはオフです。

Statistics File

ファイルの保存先を指定します。デフォルトは3delight/<scene>/<pass>.<ext> です。TIFFでレンダリングする場合には、TIFF名を指定することで、ファイル内にStatisticsを埋め込む事ができます。このアトリビュートを空白にすると、Standard Output (stdout)にStatisticsが出力されます。

Log Render Progress (in console or log file)

オンにするとレンダリングの進行具合('stderr')をコンソールに出力します。書式はシンプルで"0%  1%  2%  3%  4% ...  ... 98%  99%  100%"と出力されます。
Render ModeがExport RIB File and Renderの場合ではRender Log アトリビュートで指定したログファイルに書き込まれます。
WindowsOSではコンソールはMayaの"Output Window"になります。このアトリビュートは、デフォルトではオフです。
