- In this After Effects motion graphic tutorial we are going to be taking a look at how to do get a radial scaling effect in after effects using a Gradient Controller. This technique uses expressions to allow for a gradient ramp to control the scale. Although this may seem easy and simple, there are a lot of really great layer controls available.
x = thisComp.layer("Gradient").sampleImage(transform.position, [.5,.5]/2, true, time)[0];
100*[x,x]

Editor's Note:
Radial scale in after effects utilize a gradient to control the scale on dependent layers. How to setup and use a gradient in after effects is essential for the use of an advanced shape or object scale system. We will show you the easy way to produce a gradient and how to use that gradient to control the scale in this after effects scale tutorial. Learning how to scale in ae is important, but learning how to use a scale controller in after effects give you infinity more control. Keep on using the scale feature and I hope you learned a thing or two from this ae scale tutorial. Thanks!

I had this idea in my head to use luminance values to animate a logo and I'm so happy I found this tutorial so quickly. Wish the rest of life could be this easy.
This is beautiful. Thank you for making this tutorial (looks incredibly complex but under the hood is a clever and easy to replicate solution).
Awesome dude, this is super helpful. Like your description too, so informative.
I spent 2 days trying to made this thing in repeater... And finally CZcams recommend me this video.
THX man. And YT algorithm of course.
Great tutorial!
Thanks for inclusing the project file too
This right here is an awesome tutorial!
The result is mind blown!
Very cool tutorial man
thank you for making these cool tutorials
Thanks for the tutorial! Fractal noise could be pretty cool to use as a driver for this effect also.
great video as always :)
Wow! This video really helped me a lot! Thank you
Awesome tutorial. Thanks!
well done tutorial.. very clear & helpful, thank you
Really nice gradient!
amazing! thanks for this tutorial
great tut!
Thank you for making this tutorial !!
Nice tutorial , thanks
Thanks lots for the tutorial! Expressions give a lot of creativity space in AE. Huge fan of yours ✌️
Awesome! Yeah, I'm trying to learn expressions, but my man a lot of it goes right over my head. Part of the reason is there are so may expression functions that can do awesome stuff that isn't easy to find. Like I didn't even know about sampleImage until I searched the forms at CreativeCow and found motionscripts.com.
@@moboxgraphics Instead of creating the expression and then creating the grid - you could create the grid in Illustrator
create the expression on one layer. Right click on the property, "Copy Expression Only"
and the select all layers within the grid and hit paste.
thanks man! helped me a lot!
Thanks a lot! it was quite useful for me 🙌
great tutorial, thanks
cool tut!
Boi thank you!!
great tutorial!!
Great tutorial, thanks! Quick question, is there a way to attach that expression to the colour? So if I want the colour to be darker when its smaller and brighter when its bigger?
OMG this is brilliant
In place of a black & white gradient, you could also use the fractal noise for more wilder effect.
So siiiick. Thank you!
Very nice.
Great tutorial! I've been looking for ways to use expression in motion graphics.
Dan Ebberts the god! Love the video! tks
Thanks, help me a lot
You Just saved me a lot of time
Very helpful
beautiful
GJ I LIKE IT!
Thank you bro!!! Спасибо!
9:14 - Now the size controller seems to scale the dots around an invisible anchor point I can't change? In your video they shrink down to the center of the shape.
Just a secondary thought and obviously super late in the game here! But if you precompose the shape layer and add your expression to that, you could easily change out your shape later on and not have to duplicate and line up all those layers again. Would love to hear your thoughts. Thanks for the tutorial!
This is exactly what I did it works way better only issue is still the grid is a nightmare and if you ever want to change the amount in the grid good luck
So, what would this look like if you wanted to change the Y Position relative to the gradient color? That is, if you had the grid set up the same way, but you want all the circles to do "the wave."
7:52 - Size control layer stops working. Wont let me adjust the size of the shape with the slider control anymore?
Would this script be able to be used for example to position a layer in 3D space? When I enable 3D on the layer, I get the error message of "argument 1 to sampleImage() must be 2 numbers".
I'm guessing I need to add in another parameter somewhere since the scale now has 3 parameters instead of 2, but I really can't figure out for sure where that is. The expression works perfectly when 3D is not enabled.
Thanks for the tutorial!
Really cool. I've been wondering what all you could accomplish by tying seemingly unrelated properties together. Nice example.
Yeah sampleImage is a new one for me, but it certainly offers a lot of creative freedom. During my research I found people creating RGB color pickers and much more. Really cool stuff
Thank you
Was wondering what it would look like if it was opacity linked to the white level of the other layer instead. So it would sample any area of a noise layer or gradient and would vary in opacity as it travels around the screen.
This expression doesn't quite work for me in Adobe AE 2021... For some reason it causes my shape layer to change position as well as scale (I have applied the expression to Transform -> Scale). If I adjust the gradient from white to black, then the shape will start in the center of the composition and move toward's it's original position in the comp whilst also changing scale from 0 to 100%. Any idea what is causing the position to transform as well as scale?
Thanks a lot, i've a question, why you didn't use a repeater for a dots, and duplicated them manually?
Hey is there anyway I can animate individual paths within a shape in this way? cheers
Any idea how to add colour to this? Meaning when the object gets smaller it changes to a certain colour? really need help )
Any tips on how I could make this work for a 3D layer?
Hi! Where cool tutorial! Can u advice how to use this method for 3D layers in AE please?
Trying to figure out how to adjust this to work on a 3D layer, but get it to change the orientation. Suggestions (ima go back and watch a few more times, think I might've missed something that answers that)?
Tks!!!
Super Nice
In the case of a lot of layers in a comp, the render time with this expression becomes very long, even with 32GM RAM. Is there a way to make this expression less RAM heavy?
Legend
Does anyone know if this works to control opacity as well?
Question: How would you use this to affect the position of the shape layer. I.E. Like you would with a cloner/plain effector in C4D.
I just worked this out... Instead of a gradient layer though I have "FN Layer" as I'm trying this with fractal noise...
POS=transform.position; //position of current Layer
x = thisComp.layer("FN Layer").sampleImage([POS[0],POS[1]], [.5,.5]/2, true, time)[0]; // Returns the 0 value of sampleImage() Array from this layers position on a fractal noise layer "FN Layer"
[transform.position[0],transform.position[1],linear(x,0,1,-1000,1000)] //Specifies the return of values leaving x and y position unchanged and editable while making the z value fluctuate back and forth in space when var x goes from 0 to 1, will adjust the z value from -1000 to 1000
What do I do; when I off my gradient, the circles are gone?
Can I use this video to make sound effect on this point?
Thanks bro you really help me :-)
It's a little complicated and kind of slow, but I don't see another way to do it and have as much control.
MOBOX Graphics i have a question bro do you know someone who can shout out my channel???
Here's the biggest tip I can give someone first starting out:
Have something to offer. The only way to get someone to give you something is to have something of value to give in return. For large channels, that is exposure, for smaller channels it's a bit harder. You need to be able to offer technical skills, quality, specialty abilities. Something. Big channels get 100+ messages per day about shoutouts or collaborations. Demand is high, supply is low. Differentiate yourself, bring something to the table and make sure you have something to offer. Best of luck to you!
MOBOX Graphics Thanks bro great tips i will follow them thanks again:-)

How would i write the script to alter the vertical position of the letter, rather than its scale?
So it only moves up and down on one axis
Cool! Would it be possible to control Stroke Width, with this expression?
Is there any possibility to create this in Photoshop or illustrator? I need exactly like this, but controlled by the black/white value of any image/mask.
What do you click to see that panel in size? (Im spanish, sorry for the bad english)
would it be possible to make a 3D version of this expression by altering the Z position instead of the scale?
This gradient expressions doesn't works , i copy it , but after past, it says effort. I use AEcc2014 , is that my version due to this effort? rsvp~
i did not understand the text about fill and color changing that shows up at 3:03 . anyone?
Hi.. Thank you, man, for this great tutorial. Is it possible to do the same thing to "Opacity" of the layer.? If yes, would you please tell how to change the expression code for that purpose.?
transform.Opacity = thisComp.layer("Gradient").sampleImage(transform.position, [1,1]/2, true, time) [0];
100*[transform.Opacity]
@@Bbnvts Thank you so much. I'm gonna try that out. Highly Appreciated.
any ideas on how I could map this same expression to control rotation?
Maybe you should apply expression to rotation, but not to scale how it maded in video
Thank you very much for this tutorial. Any idea why if I parent the dots to something the expression dies? I need to also rotate them linking them to Null but some of them disappear if I parent them...
I don't think the expression dies... but when you parent something - it's position value changes from where it's currently at relative to the top left corner of the comp - and now the position value is relative to whatever you have now parented to - so now it's sampling in a different area.
Hi! Awesome tutorial! I have one question, I'm trying to change the gradient wipe to a black/white image (jpg), but it doesent work. It makes the dots scale at wrong place. Like as if the image isnt where it is showing on screen. Any ideas?
It doesnt work if you have the images you want to scale with the gradient are picked to null object. Had the same problem today.
I am really struggling to get the expression for colour sorted
Can this be done with just opacity instead of size?
heyy! thank you so much for this tutorial! i did it perfectly (only took a couple tries lol) but i am also trying to figure out a way to add a full image inside these circles. Do you know how to do that? i want like the image to somehow make this effect by being inside of them somehow. idk hopefully that makes sense haha
Wouldn't making the circles precomps instead(and resizing the precomps) and then masking the photo to the size of the circle work?
This is super late but in case you are still interested: Place your image at the very top of all the layers, then activate "Preserve Underlying Transparency" (google where that is if you're not sure). hope that helps!
here is a more efficient way using time displacement: animate the size in comp then use time displacement effect and what ever the gray scale map, then you are be able to make is 100* faster and won't slow down a bit even if you double the amount of the dots
Could you explain? I need more dots and more speed!
@@jimmyev1 using time displacement instead of using sampleimage, all the underlying layers will be time remapped according to a animated grayscale comp.
thanks...
i dont understand, as soon as i remove the gradient ramp from the gradient layer, everything stops working. pls send help
Why is the size control null needed? It isn't used at all. I replicated your tutorial without the size control null object and it worked fine.
Fantastic tutorial. Thank you! Would love to be able to link the fill color to the gradient control too. eg: the smaller shapes are green and larger shapes are red. I am sure there is a way, but my expression skills are lacking.
i know Im asking the wrong place but does anyone know of a method to get back into an instagram account..?
I was stupid lost my account password. I love any tricks you can offer me!
@Jensen Damon instablaster ;)
@Kade Matthias I really appreciate your reply. I got to the site on google and I'm trying it out now.
Looks like it's gonna take a while so I will reply here later with my results.
@Kade Matthias it did the trick and I actually got access to my account again. I'm so happy:D
Thanks so much, you really help me out :D
@Jensen Damon You are welcome =)
how to restrict thing position in range
Thank you for this tutorial, but I have a question : How can I apply this expression on the z axis to control it like you do with the scale ?
I'm sorry, but without trying it, I could not be certain. Maybe I'll make a tutorial on it soon? Keep an eye out.

I just worked this out... Instead of a gradient layer though I have "FN Layer" as I'm trying this with fractal noise...
POS=transform.position; //position of current Layer
x = thisComp.layer("FN Layer").sampleImage([POS[0],POS[1]], [.5,.5]/2, true, time)[0]; // Returns the 0 value of sampleImage() Array from this layers position on a fractal noise layer "FN Layer"
[transform.position[0],transform.position[1],linear(x,0,1,-1000,1000)] //Specifies the return of values leaving x and y position unchanged and editable while making the z value fluctuate back and forth in space when var x goes from 0 to 1, will adjust the z value from -1000 to 1000
Hi. Great tutorial! I want to move multiple objects with a null object, but when I parent my my shapes to a null, the script stops working. Is there a way to parent multiple object?
I just saw your comment as I was trying to make a similar thing happen. I had everything parented and it locked down and used the parent as the "sensor". I ended up having to un-parent it to make it work properly. I'd love to find a solution as well where the parents can stay linked
Hун bro, how to switch places?
On black to increase the shape of the balls?
So, I'm trying to replicate this effect, but using the expression to modulate the opacity of the layers. This isn't working, considering that position is two dimensional and opacity is 1. Do you know how I might translate the position data into a one dimensional form that can change opacity? Even color would be cool, but I don't know how that'd work.
learn value expression thats will solve your problem
transform.Opacity = thisComp.layer("Gradient").sampleImage(transform.position, [1,1]/2, true, time) [0];
100*[transform.Opacity]
Cool video. How do we overcome situations where there's a vector layer containing 800 different dots... Since your approach cannot work with those kinds of shapes layers that contain subgroups, how could we go about extract those subgroups as individual layers? Would probably overwhelm the program? Is there a way around that?
I think if you convert vector to shape layers (assuming that the layers are separated in Ai), you can copy expression and paste on the new layers. But be warned, this will kill most computers.
@@moboxgraphics Kind of what I assumed... thanks. Probably a practice best done in chunks...
it gives an error at the sampleImage: the first parameter has to be two numbers... How can I fix this?
Uncheck 3D box on your layer, fixed it for me
ECAbrams? Anyone? Just me?
Cool Tutorial Mobox
Yeah EC Abrams is awesome. Wish he uploaded more frequently!
how we can achieve this for lottie ?
it cant use in 3D layer >"
I can't get this to work as well as it used to. There is no gradual scale only 0 or 100, and nothing in-between. Even with a very soft graduation.
Just a tip guys - as this had me stumped, initially. If you don't see a property called "Size" with a stopwatch beneath Shape Layer 1 > Contents > Ellipse 1 > Ellipse Path 1, then - like me - you drew your shape with the Bezier Path option ticked. I simply deleted my first circle, select the circle drawing tool again, unticked the Bezier Path checkbox, then drew again. Now the shape has the Size property.
+Andrew Jaques Ahh I see. You must be using cs5? Bezier Path is no longer a toggle in CC. Thanks for the input!
CC 2017 Trial - same as you I think :) With Default workspace it shows up in the top bar above my preview when I have the ellipse shape tool selected, ready to be ticked or not ticked.
I am at the end of my 7 day trial now though, so having picked up a lot of stuff over the last week from a udemy course and videos like yours (much thanks, by the way - loving your content!) I'm well and truly hooked and going to take the plunge on a monthly license.
great tut! thanks, but i can´t find the project file...

Why not to use repeater instead of manual cloning circle?
I have just tried it with repeater, it will not work :)
7:22 what do you mean by "I'm turning this into a string"? I can see from some research it seems to do with Python but I'm an After Effects guy and I don't understand what is happening or what that means. Some explanation would be much appreciated!
Sorry, so basically [0] means I want the first component of the string. The string is [0,1,2,3] so basically they are the components of the color information. In this case it's 0.51 ish and I want the first value [0.51,x,x,x]
@@ekimoleksander6068 That makes sense, thanks for explaining! I'm used to the [0] being like position x and things like that.
Great. How to add circles opacity in same way? Thanks
