Read the scripting guide again. Expressions are simply layer properties and can be added using layer.property and layer.property.expression or something like that. Still not particularly convenient, as you have to add all the extra stuff for line breaks and special characters inside the expression s...

No, they can't. You have to use sampleImage() or some other workaround to find the layers border pixels.

That's completely pointless. The actual buffer size and memory consumption is rarely ever related to a perticular layer. It just as much hinges on effects that fexpaqnd/ dilate buffers or do blending operations. Enbale "Plus per Frame info" on your RQ and see where the render stops. That's...

You need to create another loop that forces the expression to evaluate for every frame while(x < thisComp.duration){}.

Does it not work because of the rotation order? Anyone tackled this before? I'm crap at vectors, 'cos I never learned that stuff at school (but then again I'm crap at most math stuff), but I would assume that you would need a cross product based on the first two vector components somewhere to get a...

Nucleo Pro copycat again? Sure sounds interesting.

Is it possible? Umm, no. Not in the way you want it. The requirements surrounding it are way to restrictive to make this a worthwile effort. a) scripts and expressions have no access to font face, spacing and other text information b) based on a), it would have to be done with masks c) based on b),...

Well, those are nobel goals, but I think this would be impossible to pull off. What you want is analytic and process-oriented structured thinking and that can't really be learned this way. Teaching people how to disect and break up a problem into small steps goes way deeper than just organized code....

Pretty much the same applies here.

camSource=thisComp.layer("Camera").position; footSource=thisComp.layer("Footage").position; minDist=0; maxDist=500; minBright=0; maxBright=100; distance=length(footSource,CamSource); darken=linear(distance,minDist,maxDist,maxBright,minBright); Tie to whatever parameter you need ...

m3D=thisComp.layer("3D Layer");
m2D=m3D.toComp(anchorPoint);

What am I missing? The return value from the slider is not rounded automatically which renders your substring defunct. As Paul already pointed out, you need to declare it explicitly as a math value to make JavaScript's automatism's kick in. Expression controls as such are just dumb elements that re...

Dan Ebberts has exactly what you need on his website http://www.motionscript.com.

Use the audio as a multiplier to normal playback rather than the value itself. Other than that you will have to reduce the number of keyframes to the most distinct ones, access the keyframe values directly and interpolate on your own. All of that can be found as an example (for markers) on Dan Ebber...

I have the Globe 2-D map in a Pre-Comp, so I can add there a NULL object to the point I want to track, but the question is how on earth (...:-)) can I track a point that is transformed by the CC Sphere effect to a different point on screen ??! Wrong approach. Place the pin using long/lat in the com...
