So-- Brian, I downloaded that ffx way back when this thread= was active, only to have it not work and promptly forgot about it; just= checked and realized it was made in this latest version of AE CC, and so= was locked to early testers 'til now!=20

Thus said, looks great.

Subject: Re: [AE] Doppler Weather Graphic

Honestly my first approach would not be particular, but a= series of stacked shape layers, each with animated fractal noise scaled= really small on both alpha and color channels - this way you get individua= l control of colors, independent animation for each color (not tied to colo= rama map) and then parent it all to a null for overall animation. Mettle= Freeform pro could come in very handy for shaping the overall forms in = real time as well. =20

Particular could definitely work, but you may find yourself with some= very particular challenges when doing something like this.

Pun definitely intended.

I=E2=80=99ve followed the same general direction as you sugg= est Chris but used Particular to generate the basic movement with a Mosaic= preset on top. The preset was a great start point as it uses Fractal noise= , Mosaic, Median and Tri-Tone which is perfect as I have a palette of 3 = colours. I then added posterise time onto an adjustment layer for the whole= comp. =20

Much easier to create than I had imagined.

Cheers.

Well these sorts of questions are alwa= ys fun=E2=80=A6 here's thinking out loud:=20

- I'd be thinking about how these types of images are generated. = ;I'd work greyscale and then use colourama at the end. You could eyed= ropper the reference still to get the same colours.

- The images are quite low res, and I'm guessing quite low FPS. = So I'd use the mosaic effect to make it blocky, and posterise time (either= the plugin or as a time remapping expression) to reduce the frame rate = of the animation

- There's a subtle bend in the graphics. There are a few options= for this in the distort effects, including CC bender, CC bend it and the= old stock favourite Polar Co-Ordinates.

- I'd do the actual keyframeable animation in a pre comp. It = could be as simple as white blobs on a transparent background. You= might be fine with animating masks on a solid, or using several small soli= ds. But start with a simple base composition that has just the bits= you need to control. Then add noise and grunge in another compositio= n - you can always use fractal noise, turbulent displace, roughen edges = to create a grungy version. Remember - greyscale is fine. add= colour at the end, that's how the real stuff is done.

So:

1) Base pre comp with the main elements

2) Grunge version

3) Add mosaic effect and posterise time

4) Bender / bend it / polar coordinates

5) Colourama

Have fun,

Hi,=20

I think I vaguely remember this coming up once before on = here. I need to create and animate a Doppler radar weather type = graphic. Similar to this:=20

h= ttp://www.crh.noaa.gov/images/arx/top10/fayette0525.png

I need to be able to control its centre point and also the positi= on of colours. The centre of the 'storm' would move between predetermi= ned points over time. =20

Feels like a job for Particular but I'm unsure of the = most efficient way of going about it. I have 27 different positions for = the 'storm' to move between in a minute so ideally the only manual key fram= es I'll be pulling will be positional.

Suggestions for start points appreciated.=20

Thanks.
