Try this: n = position.numKeys; if (n > 0){ t = time - position.key(n).time; if (t > 0){ freq =8; amplitude = 50; decay = 2.0; //s = amplitude*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t); e = amplitude*Math.sin(freq*t*1*Math.PI)/Math.exp(decay*t) value + [0,e] }else{ value } }else{ value } Koby.

Hi Jimmy, You could make the expressions only once (for the first layer) and then select those properties you've made expression for (rotation and scale) (using CTRL you could select multiple properties), copy the expressions by: Edit -> Copy Expression Only and then paste them to all other layers b...

Hi Stefan, I don't know how to access mask vertices via expression... I don't think it is possible... As for writing the position of a layer in a text layer, there shouldn't be any problem using the expression you wrote... just make sure you apply it to the "Source Text" property of the te...

Hi Stefan, I didn't mean you take the script as is, I meant that you see the way he takes the values from the vertices... see on line 160, it should be something like: var comp = app.project.activeItem; var mask = comp.selectedProperties[0]; var maskShape = mask.maskShape; var shape = maskShape.numK...

Hi Stefan,
Check out nab's script "MaskVertexExpression" here:
http://www.nabscripts.com/downloads_en.html
(script number 16)
That script changes the position of mask's vertices (watch the demo file).

You could insert the maximal wiggle amount you desire, and then multiply the wiggle diviation by a slider. Give this slider values between 0 - 1, and add keyframes to this slider in places you want the wiggle to start and end. This way you will get a smooth and controllable wiggle. I mean something ...

To set a value, use the setValue method. For example for a value of 17 use: app.project.item(1).layer("whatever_0000.tga")("Effects")("Fast Blur")("Blurriness").setValue(17); If you want to add a keyframe at a specific time, use the setValueAtTime method. For ...

Uli,
maybe you could ask Lloyd Alvarez to add this feature to this BG Renderer script in this post:
viewtopic.php?f=3&t=544
That could be a very nice feature to his great script!

Koby.

p.s.: You could find his script also here:

I saw your problem. By the way, in AE CS4 it runs with no problem... The problem is that in CS3 the name of the composition cannot exceed 31 characters. And because the name of each composition is given according to the second string in your file, you get too long names... So if you are using CS3, w...

Great work Mathias !!
I really loved that !
Thank you.

Barry, I guess you are doing something wrong, because I've checked again and it works great on my machine... Remember, you have to have the first 3 layers in the comp as your text layers, and the text file should contain exactly 3 strings of text in each line divided by ";" (beware of thos...

Barry, I've changed Steve's script so it will read and change 3 lines of text. Check it and let me know if it works for you. Don't forget to prepare 3 text layers as the first layers in the comp, and 3 strings divided by ";" in each line of the text file. p.s.: The names of the new comps w...

I had too difficulties at the beginning downloading the project file using Internet Explorer. For some reason it opens it as an html file (with strange symbols)... I don't know why, but the link is correct and I succeeded downloading it using a different software installed on my machine. I've downlo...

dkvfx, I've check this expression and it worked for me ! I've used the same scenario you've described: 3 Null layers in 3D space in order to position and orient a solid according to them, and it worked great. Note however for a few things: 1. You have to put the 3D layer JUST below the 3 Nulls. 2. P...
