It should, the fact it isn’t means something went wrnong with running the script. Best I can suggest is try again. If that fails, try a really simple rig set up to see if the problem is DUIK or something to do with your layers.

I think Particular’s bounce options are probably the best for the barrier. But if you want to slow them down instead of smacking into a wall, then maybe take a look at Particle Playground’s Property Manager settings. These will get you a slowing down gradient. I’d use a second layer for the “rain” to appear to be generated from the first particles and finally for the logo resolve, I’d time reverse a precomp of the logo exploding into dust – so that it forms instead.

Very true Mads. Subscription models like Maxon One being twice the cost of the full Adobe Creative Cloud suite must be limiting uptake to companies only

I saw this post just before I had to disappear to a trade show (urgh) all week. And building on Hector’s reply, I wondered if the Wayback machine would supply some answers.

The latest I could find was from 2017 and the page doesn’t list Alpha Space or Alpha Holes:

https://web.archive.org/web/20171023202850/https://www.redgiant.com/products/trapcode-suite/

At least not in the Trapcode Suite. But if Hector is right and the developer is listed as Red Giant, they acquired the Trapcode plugins to go alongside their own.

Nothing obvious was listed and most of their suite of plugins still exist today. Dead end.

But then another search for “red giant” holes turned up this old page:

https://www.bhphotovideo.com/c/product/336937-REG/Red_Giant_PRIMPACKFD_Primate_Plug_In_Pack_Keying.html

with this feature:

Composite Wizard Miracle Alpha Cleaner
Clean grain and fix "holes" in your alpha mattes in one easy step.

This might not be a reference to your missing plugins, but given the name Alpha Holes, I’m wondering the old project was using something a simpler choker effect to improve a matte?

Edit:

I found a little more, could it be Red Giant’s Primatte Keyer:

I’m going to share this link, to an article on School of Motion about building the best After Effects PC. The writer spoke to engineers at Adobe to find out what AE uses. Even though the article is a couple of years old now, the reasoning behind the tech still stands.

Hard to confirm without seeing your full project, but I think this does what you’re after:

a=0;
b=3;
nam = "3 4";
var CnameArray = [];
var opac = 0;
for (var i = 0, i < 31, i++) {
	CnameArray[i] = thisComp.layer(i).name.substr(a,b);
	if (CnameArray[i] == nam) {
		opac = 100;
	}
}

Thanks for coming back to share the solution, next time someone is struggling at least they’ll get an answer.

I can’t get any animation in that gif to play, so it is a bit difficult trying to figure out what you’re hoping to achieve, but at a guess, I’d suggest taking a look at the linear expression.

This lets to map one set of values onto another, something like:

var newScale = linear(“moving layer’s”.position[0],250,500,100,25]

[newScale,newScale]

So you could take the moving layer’s position and as it’s X value (position[0]) moves from 250 to 500, the scale drops from 100 to 25.

I think precomposing the object with the mask in the precomp should have worked. Can you post some screenshots, it might help to spot the issue.

Eek, that sounds tedious.

I’m not sure how these are stored, but the good news is you have a way to delete them one by one, which means it should be possible to automate. Have you tried ChatGPT to create a script to do it? I’ve found that for repetitive stuff the this, you’re more likely to get a solution.
