Im trying to rotate a lens flare effect in After Effects that I added to a logo.

Everything I try rotates the whole image, not just the effect.

Any help would be great.

Thanks

What did you use to create this flare effect?

It's a stock effect in AE.

When you say "rotate" do you mean that you want the flare circles to turn or do you mean that you want the inner and outer flares to move with respect to each other.

If the former, you can't do that with the standard AE lens flare effect, at least not by direct means. If the latter, you can do this by keyframing the "Flare Center" parameter.

I wanted to have the main spot of the flare remain constant and have the outlying rings move around that spot.

When I applied the lens flare effect to my logo layer and try to rotate it, it rotates the whole layer.

I actually just found a way to do it.
What I did was make a new color layer in black switched the mode to "add" and then put the flare effect on that layer. This worked out fine.

If you know of another way I'd be interested in hearing you're opinion.

Thanks

Whatever works for you, Kev!

What I was suggesting is that you keyframe the "Flare Center" parameter in the effect over the desired duration. I might, for example, place a keyframe at every 1/4 point in the clip with the center relocated 90 deg. at each point.

This would produce the same result that I believe you've accomplished but without requiring a separate layer.

BTW, if you see a real camera lens producing such a flare spin, chances are that you're looking at a camera (and operator) in big trouble. <g>
