I checked the spatial interpolation and when set to linear it wouldn’t work either. I was intrigued by your message saying that you cannot replicate the error, so I went to a different version of AE and it worked. At the office where I’m working, we have to use AE 2018 still for some projects and the error is showing up in that version, the current version of AE work as expected, I’ll upload two images, the first one is the graph editor of AE 2018, the second one is AE 2020 (17.6)

the null option would work that’s true. I know it because when using the expression with position properties works well, and just to be sure you can separate dimensions to make it work perfectly. However, I am intrigued if there’s a way to say loopOut to only one dimension inside the expression or if there’s a tweak to make the expression work directly in the property.

Hi Dan, thank you for your help! I tried the .selection method and it’s more optimized indeed. it does the iteration better without any miss elements.
The problem with the UNDO feature remains though. this script works perfect the first time. but if you undo and apply it again, it won’t make the setProxy part on any video element you have on your project file and it will give you the error “unable to call setProxy because of parameter 1. Value is undefined”.

This is the code as I have it now with the .selection property.

app.beginUndoGroup("placeHolderAndProxyToSelf");

var pItem = app.project.selection;

for (i=0 ;i

I reduced the script so it’s easier to read and tried to remake the FOR sentences to be cleaner… I save the sources in an array first and then convert everything to a placeholder. finally I set the proxy for the placeholder based on the sources array.
But the problem still there and is the same error… If I apply the script on a new file with some files imported, it works the first time, but if you UNDO and try to apply it again… doesn’t work.

Could it be that After effects doesn’t update correctly the sources files after undoing?

also… the base code to set proxy always work… the problem is just when I try to add the feature of replacing with placeholder.

app.beginUndoGroup(“setproxytoself”);

var allSelectedSources= new Array();

for (i=1 ; i <= app.project.numItems ; i++){ var pItem=app.project.item(i); if (pItem.selected==true){ var pSource=pItem.mainSource.file; allSelectedSources[i]=pSource; }; }; for (a=1 ; a <= app.project.numItems ; a++){ var pItem=app.project.item(a); if (pItem.selected==true){ pItem.replaceWithPlaceholder('placeHolder',1920,1080,30,3) pItem.setProxy(allSelectedSources[a]) }; };

That looks great! if you can share that I will really appreciate it! it does looks more organic than the standard cuts.
Thanks mate!

Thank you very much! I didn´t see that. I was punching my head because all the time I thought that the problem was the shadow catcher.
Thank you again!

these two codes are amazing! thanks a lot Dan!

Thanks a lot Dan! that does exactly what I needed.
Is there a way to go further and make this expression work when you link at the middle of an animation?.
I was playing with nearestKey(time) but I didn’t accomplish anything so far.

Thanks! this technique is great! although it doesn’t allow to place the gradient whatever you want, it’s great to generate an effect of gradient going from the center of the object to the edges. Nevertheless I used a simple gradient placed in the the polygon and so far it works… the only thing is that doesn’t look exactly like the reference because it overrides the edges of the object, painting all along the geometry as if were outside, not inside.

Thanks.

Thank you for your response! turning the shadows on for the button lights really changes the way they interact, it is very interesting. you are correct about the tint on the shadow from the transparent part of the buttons. although this is for a client which doesn’t want that. So I guess I´ll do a different material for the buttons when they are off, and then combine the renders as I like how they look turned off right now.
Thanks a lot.

Matz.
