Error – no active camera?
I’m using AE CS6 (v11.0.1.12) and have a strange error that I see has occured before in one or two posts.
I’ve applied the auto orient on Y axis only expression from Dan’s site (thanks yet again Dan!) to the Y rotation of an illustrator layer. The comp is a pre-comp but has an active camera in both the main comp and pre-comp.
I get the following error and the expression is disabled:
No active camera at time xxxxx
At first it was always at time -00:00:00:01 but then I purged all memory several times and then re-entered the expression. I briefly got it to work and the layer oriented in the Y axis but without touching anything, several seconds later I got the same error but at 00:00:20:00.
Very weird – got to be a bug maybe unless I’m missing something?
Any ideas?
Thanks,
Paul.
delta = toWorld(anchorPoint) - thisComp.activeCamera.toWorld([0,0,0]);
radiansToDegrees(Math.atan2(delta[0],delta[2]))

I’m not seeing that error, but you should be able to work around it by changing activeCamera to layer(“Camera 1”)

Many thanks Dan,
That solved it for that time – I’m still seeing the odd occurrence which is fixed by simply re-pasting in the expression (with activecamera) – something whacky going on somewhere!

The other thing you can try is wrapping the expression in a try/catch construct, like this:
try{
delta = toWorld(anchorPoint) - thisComp.activeCamera.toWorld([0,0,0]);
radiansToDegrees(Math.atan2(delta[0],delta[2]))
}catch(err){
value
}

Does that only then evaluate the expression when there’s no error – therefore not disabling the experession if something odd is going on?

That’s correct.

Great thanks Dan – will try that next time.
