Hi guys, I’m trying to automate a trail for a simple object (in this case a yellow star). I would like to get the following (this is a faked mockup) where a yellow star follows the black path: [Screenshot 2023-08-06 at 14.03.43] I think the best option would be using “motion blur” layer, but I c…

Yes, I also made this option when playing with @Kai ’s suggestion, but as said it’s not smart, hard to draw and animate… the best option is going to be the one with the new feature, it will allow to “echo” anything you want effortless and it will always follow any path or animation the parent does …

Are you talking about something similar to this one? Was bored, so doodled a girl in synfig for you guys - #85 by Kai

No exactly, this is what I want to get: [example] I would like to control the number of “subsamples” and their separation. The motion blur layer is perfect for this task but as I can’t control the transparency I need to “hack” it by duplicating the layer as many times as needed to get an opaque re…

That looks like this. Was bored, so doodled a girl in synfig for you guys - #55 by Kai I’d created this using duplicate layer.

Yes, I think that one is what I’m looking for. How you made Duplicate layer follow the path?

I linked the group layer to the spline, opened the transformation parameter of the group layer and converted the amount parameter to add and then linked the index of the duplicate layer to the addition sub-parameter of the converted amount parameter. That’s it. [image] nnmdragontail.sifz (6.3 KB)

Hi @Kai , I’ve been playing with your workaround, it works but it doesn’t behave like a real trail, for instance, in my example the star goes forth and back and the “subsampled stars” follow what the parent star did. In your solution, it doesn’t. It’s also pretty hard to make it work as you want so,…

[image] bjyitu: Maybe this one is what you are looking for? Thanks @bjyitu , it looks like it’s the same approach as @Kai , it has the problem that you can’t make your object bounce from the last point of the path to the initial one. Look how my “example.sif” star moves from left to right and r…

No exactly: in your example the circle “waits” in the right side to the subsamples to “arrive”, then it moves back to the left side. In my example, the parent star (or circle in yours) bounces in the right side and heads left but the subsamples still go right and start going left then it’s time to.…
