1.先把原本Maya light的Attribute的intensity數值改成跟Renderman的light shader的KI的數值一樣
2.把Renderman的light shader的KI按左鍵從"internal Valeu"模式改成"TCL Expression"模式
"

3.在KI鍵入 [mattr "bulbShape.OnOff" $f]
4.把滑鼠游標移到Attribute的intensity點擊控制bar後,打開Script Editor把下面setAttr "camSpotLight13Shape.intensity" 0.9;語法裡的"camSpotLight13Shape.intensity"這段字 給copy 貼入KI[mattr "bulbShape.OnOff" $f]裡面參數替換成[mattr "camSpotLight13Shape.intensity" $f]
5.接下來就可以在Attribute裡面的intensity set key了。
