Hi guys.
I'm working on a graphic design stuff and I have a question for you

My animation begins with a simple circle. Then the circle multiply itself to, let's say, 50 circles and all of them should be aligned on a ring. The diameter of the ring begins small and ends quite wide.

So to multiply the circle, I wanted to add a repeater but the problem is that I can't move these repeaters on the z axis or along a path, wich means that I can't create my "ring of circles"

I also tried to use a video copilot preset (the 3D orbit). I put it on a null, parent my circle to the null and align the orientation of the null along the path, etc ... but I have to copy and paste 50 circles and I can't work on the diameter of my "ring"

Aaargl!!!!

Does anyone know if I could do this with the repeater?

Thanx

[Marc De Coster] "Does anyone know if I could do this with the repeater?"

i don't think so... as you've found, the individual shape (contents>'shape') transform properties are only 2d, and thus the repeater only works in 2d.

so i think you're looking at creating 50 3d circle layers, offsetting their anchor points and rotating them around their x axis.

to easily increase the radius of the ring, you can link the anchor points of the circles to the anchor point of a single circle with an expression like this:

L = thisComp.layer("Shape Layer 1"); // this would be your first circle, or master, etc..
L.anchorPoint;


if you keyframe the first circle's anchor point, any circles with this expression will follow.

if you need to control the x axis of all of them, i'd add an angle expression control effect to the first circle, and then try an expression like this to control the rest of the circles:

L = thisComp.layer("Shape Layer 1"); // this is your first circle
i = L.index;
L.effect("Angle Control")("Angle") * (index-i)


you should then be able to control the x axis rotation of all the slave or follower circles from that one control.

Mmmmmh, that's exactly what I was afraid of ... expressions !!!
I know that some day I'll be obliged to work on it but right now I know that expressions don't like me :-)

I've tried what you told me but I must f*** up somewhere and it doesn't work

Well, I had a good night and I had a revelation! I'll work with Element 3D! I'll use my circle with no extrusion and then I'll use the particle replicator. I'm sure it'll make it

Anyway, thanx a lot.

I'll post the result (if it's good!!!)

The Text Tool might be a viable option.

Yes I thought of that. Maybe letter O with a big stroke to fill the hole ...

I'll try

Thanx

Is that what you want?

Thanx but no, it's quite more complicated than that. The circles shouldn't be flat and they should appear from the center of the ring

But it's OK I've found a solution

Thank U

Would be nice to know what your solution was.

wow, that was an old one!

You're right, I should have kept you aware of what I did.

As I said some posts earlier, I used Element 3D. I created a circle mask on a solid, extruded it in Element, added a replicator shape "ring" and animated the shape scale in the same time that the particule scale (that was also rotating on itself on the y axis if I remember well)

I don't have the result right here but I'll try to find it back and post it

Talk to you the next time I'll have an issue, it'll happen soon enough :-)

Marc
