Can't key light intensity.

Whenever I try and key light intensity it changes the key values. So they all end up the same. It's starting to bug me. Is this even possible?

Are you changing which frame you're keying it on? If you just key the intensity on the same frame, then obviously no animation is taking place.

You might wanna check if your light have any input connection that control your intensity. sometimes you can accidently connect stuff..

Also check if your lights attributes have been locked (will appear grey in the channel editor) - if that is the case, then select the attributes and right click them and select unlock ...

You could also check if your light have any animation curves attached, if the curve is set to be a "Step" curve, then your light will not change until suddenly and you might wanna make the curve to be a smooth or a linear curve..

That is all I can think of at the moment.

Hope you figure it out, good luck.

yes, I am changing the frame. for example I'll do this:

go to frame 1. change light intensity to 0, key selected.

go to frame 25. change light intensity to 1, key selected.

go back to frame 1 and see that the intensity is now 1.

you dont but that's not the point. Obviously, I'm not making a scene with just a light.

He doesn't need to have auto-key turned on if he's keying frames manually with "key selected". The steps he gave above should work. I just threw together a quick scene with a couple primitives and a spotlight....intensity keyed just fine.

What puzzles me is the "lighting a scene with no geometry" bit. What exactly are you trying to light? My advice, just add a quick primitve to your scene and use that as a reference so you can see the keyed intensity.

Anyway, all you have to do is this (if it doesn't work I don't know what to tell you):

1. Select the light...click frame 1 and click "intensity" in the channel box. Right-click, and "key selected." The box should turn orange.

2. Go to your end frame and select it. Adjust the intensity value. Key-selected again.

Should work.

Here's the scene file I threw together. Maybe it'll help you.

That's exactly what I have been doing. This is really puzzling. I'll have a look at your scene and see what happens.
