thanks for that kevin, yes i’d found that one while i was searching for cornerpin expressions. This will just link the pins directly to the 3d nulls position but not allow you to adjust the relative positions of the nulls compared to the pins. I use this expression often for making shine into 3d volumetric light.

Hi, I’m trying to get this work around going:
https://www.loopoutcontinue.com/2012/05/faster-raytracing-in-cs6-while-rendering-in-the-background-ymmv

Need to fix this cuda aerender problem but I can’t find the “Debug Database.txt” file? And not sure where the ae pref folder is to create the file if it doesn’t exist. Anyone shed some light on this tantalisingly vague tutorial?

[Harry Hoag]

Sorry, I don’t know of a way of doing this but if anyone does it’ll be really useful. Particularly for 3D layers where using the pan behind shifts the anchors zpos

this is something that should be build into after effects but you could use this expression as a work around. (it’s a bit crude maybe someone can make it better).

on a 2d solid’s position property put this:


a = transform.anchorPoint;
p = transform.position;

x = p[0]+(a[0]-50);
y = p[1]+(a[1]-50);

[x,y]


You’ll need to put the anchor points starting position in place of the 50s (for example on a default 1920×1080 solid you’ll need to put 960 and 540)

Hi,

yeah that’s what i’ve been doing, i was just wondering if there was an even quicker way, coz i have 450 of these to do.
Also is there a batch process in illustrator like in photoshop where you can record a few actions then apply it to lots of files?

[Harry Hoag]

cool, thanks for your help, i’ll give that a go. But i’ll be doing the same as that other poor hapless fellow, i’ve only got illustrator for the mac.

[Harry Hoag]

Not sure i know what you mean. Actually i s’pose i don’t know what you mean by polar coordinates?

sounds like a crazy amount of jiggling around if the range is 90 to 270 degrees…

[Harry Hoag]

ahh, cool cool cool,
my knowledge of expressions just increased by 0.0001
[x,y]
understandings

thanks man

[Harry Hoag]

ahh, i see.
Ok, I’ll use the wiggler on the other axis to give it a more random movement rather than diagonal.

But, at the moment it is only moving the first value on anything I put it on, in my case horizontal position.

How do I make it affect just vertical?

cheers

[Harry Hoag]

wow, excellent, thanks man…

I see what you’re saying about a 2D movement, although that would be useful. What determines the whether it’s shaking horizontal or vertical at the moment?

Because I could simply apply a horizontal shake to the object itself, then make it an embedded composition and apply a vertical shake to the embedded comp…

[Harry Hoag]

fantastic!
you were right, i had comp at 12 fps and footage at 25…
thanks man works a treat!!
