Making Rainbow Trails off of a PNG

[Tom Daigon]

You mean something like this? (AE and Particular)

or this

I guess it would be more like the color of the first, but the detail of the second.

The mushroom also needs to spin as it goes. So for instance I set the PNG to 0 rotation, then moved the cursor to the end and set it to -1. Then I pre-composed the layer, but still didn’t see any trails when using particular, and selecting the layer as the particle.

Thanks Tom!

Glad to help Matthew. Heres the CS6 Project if you want to analyze it.

Thanks Tom-
I am looking forward to it (have a few client things to handle for a min)

Alternatively, you can achieve some rainbow trail effects using:

Echo + Coloroma

or

CC Time Blend FX + Hue/Saturation

These methods both have what might be significant downsides* but they may also be exactly what you’re looking for 🙂 So here’s my contribution in project file form for your perusal:

I used solid colors in the Time Blend FX example but you could also tritone the image instead of using fill and then rotate the hue in the same fashion.

*The blending when using Echo isn’t ideal. Time Blend FX uses previously cached frames and so sometimes misbehaves. It also is not compatible with render multiple frames simultaneously.

Thanks Darby! I’ll check them out.

I really like the echo + colorama Darby, it’s perfect.

Now I have done many things in AE, and maybe I am just not getting a basic concept, but How did you get the FX to apply to the layer without being a part of the comp itself.

Admittedly, AE is a hobby for me, not a full time job, but like I said I have made some pretty advanced comps in my time. Maybe I am missing something pretty basic?!

Maybe I should be in beginner guys, BUT i tried applying echo to a pre-comped spinning Mushroom, and no luck. What the devil am I doing wrong?!

I did watch the tutorial including nesting and precomposing. I did pre-compose the layer but the echo still shows no effect.

I made the Rainbow trails using Particular. Hope this may help.

You need to apply your transformation keyframes inside the pre-comp.
