thanks for the great tutorial.

i have a quick question. towards the end i saw your 3d version with particular. how do you assign z position in particular? particular has z position in separate parameter and when i use toWorld expression got an error message saying vector length doesn't match. here is my set up.

in particular...

Position XY
c=thisComp.layer("moon");
c.toWorld(c.transform.anchorPoint); //this works fine!

Position Z
c=thisComp.layer("moon");
c.toWorld(c.transform.anchorPoint[2]); //this line gives me an error. i was trying to grab only 'z'value from 'moon' anchor point.

any advice?

i can use lights for particular to trace but would like to know in expressions.

I'm glad to help. It's always nice to hear people are actually working through the concepts in a tutorial themselves, versus simply watching along and forgetting how to apply the concept.

Thanks!

Are you working with a non-square pixel aspect ratio composition?

Dear Carl Larsen

I re-checked the pixel aspect ratio. It was 0.9; I changed the aspect ratio to square and all its working fine. once again, Thank you.
Best regards

Thank you for this good tutorial. I did as it was. But there is a problem- the null object (eg. Orbit) stretches while it rotates. the linked circles also get oval shape during the animation. the beginning and ending shape is circle; but the shape will change to stretched oval when it rotates.I tried in different machines but the problem remaining.
Please advice me..
This is one of those tips

This is one of those tips I have to come back to a few times until I completely understand the principle!!

Thanks for the tip!
Trace is backwords
by Heather Hass
Hello!

I'm just doing this tutorial and im at the end, but unfortunately, write-on trace writes backwords...:(

Wondering if you had any suggestions...i triple checked the codes and i know i have them correct...

the path of the moon sprouts out of the moon then the moon follows the path instead of creating a path...hope that makes sense!

any help would be greatly appreciated! ill give you a 5th cow when i can get this guy working!

One of the best tutorials in some time! Not for it's visual impact but for clearly explaining the layer and world space principles and showing some usefull expression code.
