thanks for your help, but its not the solution.
i scale only x axis, thats fine.
but when i turn on auto orientation, the expression on orientation does not work correctly anymore and the two layers are not connected.
So I have to implement “orient to Camera” somehow in the existing orientation expression, but it seems to be quite hard 3d rotation math. here are three images demonstrating my issue:

OK, no help needed anymore, i got it.
there was a parent which scaled to zero in the end of the comp. So if this is the case write something like “parent.scale” instead or just scale not to zero but 0.001 and then blend the layer out.

[Arne Münch]

I found that one in another thread, but it doesn´t help. No scale animation involved in my case.
if ((Math.abs(scale[0]) > 0.01)&&( toCompVec([0, 0, 1])[2] > 0 )) value else 0

hi
thanks for your reply.
I have put that line to the layer positions in several precomps of my precomp.
I don´t see any benefit from it. It has to render again although nothing important changed.

But I have more expressions, working with linked colors and also the scale of several layers is linked.
Does every single expression in every layer in every precomp of the precomp need that line?
Would be a lot of work to set up.

[Arne Münch]

nice, thats it, I need to Reference to the parent layer space, not to its own..
thanks so much..

[Arne Münch]

Thank you Dan.
Yes I know, checking that ID doesn´t cause an error, but the code does´t work, the behavior of that ID is not understandable for me.

Alternative idea:
I there a command for finding an Undo Action in the protocol and and than execute that instead?

[Arne Münch]

I try to include an Undo Button in my Script but it doesn´t seem to work properly with your code. I tried:


myPanel.grp.group1.undoButton.onClick = function(){
undoFinder = app.findMenuCommandId("Undo: Shape"); //Shape is the name of my undo group
app.executeCommand(undoFinder);
var i = 0; //Variable To prevent from infinity Loop
while (undoFinder != 0 && i<10){
undoFinder = app.findMenuCommandId("Undo: Shape");
app.executeCommand(undoFinder);
i++;
}
}

I try to undo all actions which occured after "Shape" including "Shape", but the variable "undoFinder" behaves strange. Any ideas how to get that?

Hi there

Did anyone could modify Dan´s script just that it works with keyframed orientation also.
The way with Cineware is nice but not what I am looking for.

Thanks a lot..

EDIT: It seems that pickwicking the rotaion values, reset orientation and than apply expressions do the trick, but you still have the jumps (from 0|+1 to 0|+359) which makes it impossible to use smooth on the camera movement.

So it would be perfect to have a script transforming orientation to rotation and get rid of these jumps by converting 0|+359 to -1|+359?

[Arne Münch]

Clever again, thanks

[Arne Münch]

I think I have to accept that with the maskvertexexpression script it won´t work.
The script just looks at the maskpath at the actual point of time and can manipulate exactly that state.
A keyframeanimated maskpath will not be taken into account, and this is why velocityAtTime just outputs (0,0)

If anyone capable of writing such a script reads this and likes the idea, please reply here so I will know..
