Light animation

may i just ask how to animate light like blinking or growing light

normally you would animate the emit value for the lights material, unless you are talking about an actual blender lamp in which case you would animate the ENERGY setting on the object data sub panel (the button will look like a styleized sun)

just put the mouse pointer over the light colour or energy settings part and press I to insert a key frame like this u can adjust as blinking lights

  1. Insert a keyframe at the emission intensity value in Cycles material settings at the beginning of “blinking/flickering” and at the end.
  2. Open the f-curves and add a desired modifier to the emission curve. Voila. Edit the modifier settings as you please and edit the curve itself for general state of the light and you have automatic flicker.
