blender用スクリプト。使用したこと等による損害等一切無保証、自己責任でどうぞ
使い方
1 .下記スクリプトのresolution,frames,outPutPassesをよしなに書き換える
※とりあえず 初期のまま、デスクトップにでもuntitle.blendを保存して、それで試して見ることをおすすめします。
以下a,b好きな方で
2a. cmdなりPowerShellなりBashなりZshなりで ./blender.exe -b <ここにレンダリングしたい*.blendのパス>  -P resourceRenderScript.py (->このスクリプトのあるパス)
2b. blenderでレンダリングしたい *.blend を開いて、blenderのテキストエディタにこれを貼り付けてAlt+P
3. *.blendと同じフォルダに、同じ名前でフォルダが作られ、その中に結果が入ります。

注意
2.67で書いたので、他では動作しない可能性(特により古いバージョンで)
ノードの"Render Layers"の名前や中身が変わってると多分動作しません->'Render Layers'とかを書き換えたら動くかも
レンダーレイヤーも同じく名前が変わってると動作しないです。ｰ>'RenderLayer'を任意の文字列を' 'でくくったやつで置き換えると良いかも
拡張子は.blend依存・・・気が向けばどうにかするかも、
