If I understand you correctly then you might need to use the % operator.

So if n is your layer number then n%3 will give you a number of 0, 1 or 2.

For example if:

n = 1 then n%3 = 1
n = 2 then n%3 = 2
n = 3 then n%3 = 0
n = 4 then n%3 = 1
n = 5 then n%3 = 2
n = 6 then n%3 = 0
..and so on

Does that help?

copy the following expression into your Slider:

Math.floor(value);

Math.floor rounds down whatever number is inside the bracket.

I hope this helps.

Thanks again Dan. I think I’ve got my head around it all now.

I think this technique could end up being a bit of a revelation for how I work in After Effects.

That works, thanks Dan.

What do the triple quotations do?

Hi Filip and Dan.

I’m trying to use this technique but I get an error with the eval expression saying “Expected: ]”

Is there anything in CS6 that would mean that this technique would require tweaking?

Cheers,
Jamie

Thanks Dan.

As always it seems obvious as soon as someone much more clever points it out to you! 😉

Cheers Dan.

I suspected that it might be something along those lines. I’ve found this documentation:
https://www.geometrictools.com/Documentation/EulerAngles.pdf

…and I’m hoping I can work out what’s needed from there. Wish me luck!

Problem half solved.

After more investigation I have now found the problem and a work-around.

As I suspected, the issue is that the AE camera uses a rotation order of X>Y>Z while the Psunami camera uses Y>X>Z.

I started to try and work out what modifications I would need to make Dan Ebbert’s code work (that I previously posted) but I think it would take me too long to get my head around.

So instead I have simply created a work-around by parented rig system that effectively makes the rotation order of my AE camera the same as Psunami’s (Y>X>Z)

Here is a short test of that working:

https://reels.creativecow.net/film/psunami-camera-test

It has made my intended animation for the camera a lot more fiddly to do though so if someone out there does know a good way to convert X>Y>Z to Y>X>Z that would be fantastic. If anyone can help this then I would also be happy to contribute towards a definitive tutorial/script on this matter as I have seen quite a few people asking the same problem and I think a good solution really would make the Psunami plugin even more powerful.

Thanks,
Jamie
