More problems with Echo

[PopeDope]

Hi all,

Simply, I'm trying to get this effect to apply itself to this car I have rotating in a circle. I've turned the photoshop file into a precomp (per instruction last time I asked this) and it's not working again. What am I missing here? As you can see in the photo I've set it to 1 rotation, it's a quarter of the way through the animation and there's no echo. 

Help? Thank you!

Nothing wrong. You simply misunderstand how the effect works. It doesn't generate a "trail", it accumulates buffers. Hence the rotation will have to be done inside a pre-comp and the effect applied to that layer in the parent comp.

I would give that tutorial a D because the author fails to explain that the echo effect works on pixels that are moving in the layer. The author also fails to explain that Shape layers and Text layers are vectors that have to be turned into pixels to be seen. This means if you animate the transform properties of a vector layer the pixels are generated after the layer moves so Echo will work on a vector layer with position, rotation, and/or scale changes without pre-composing, but if you want to use Echo on an image, you have to precompose the animation before you apply echo.

Also, in the future, please embed your screenshots using the toolbar or drag them to the reply field so we can see them. The drag and drop here icon at the bottom of this form is pretty useless.

Thanks, Rick. Your replies are second to none on these forums. I set the photoshop file to do a full rotation, put it in a precomp, and then applied the echo effect like you said and got it to work perfectly. Also, yes I'll make sure to embed the image next time 🙂

For anyone else looking for more info on Echo or the other time effects there's more information on this Adobe Help link

This does not work for me actually. I am trying to add the echo effect on a vector image. I have the image animated with a path and a rotation. I made a precomp of my object and even after that hte echo effect doesnt work. Once I apply the effect it appears as a white duplicate on top of my real object. the white duplicate only changes (appears or disappears) when I try to change some of the setting of the effect but does not appear as the expected repeated image behind the real object. What more can I do to make the echo effect work on my objects.
