I'm trying to animate lights, or more specific: their photon intensity. It has a 'set key' option, so I assume it can be animated.
However, whenever I try to set keys, there's no keyframe appearing in the timeline. But when I look in the Graph editor, there is an animation curve visible, and when I manually click through my timeline, I can see the photon intensity values changing.
So I thought that maybe I had a problem of invisible keyframes or something.. so I tried rendering a few random frames from the timeline, to see if there's a difference in value visible in the rendered image. But all the rendered images have the same photon intensity: the intensity of the last value I keyed.
Is there anyone who knows what to do?
thanks!
