yes I know live weather forecast solutions are available, but it’s for a small local TV, and those solutions cost thousands and thousands dollars. So plan B… we are working on something with a predefined animation rendered from maya and overlayed weather data is rendered in after effects via an external file.
Actually they work with still images they receive everyday and place it in Vegas with a voice over.

Thank you Dave,

for “Dynamic” I was thinking I could have just one comp A with different images in it . Put it in different comps B1, B2, B3, .. and what I wanted is to have A react differently when used in B1, B2, B3… etc…

But I ended in using images directly in B1, B2, B3, … and playing with an expression to display the good image with an external data file.

for sure “Dynamic” was the wrong term …. as everyday I will render the project for the current day forecast with the data provided by the meteorologist

Thank you Dan for the precision. I will work with an underscore.

thanks… I checked a lot of websites about expressions but I didn’t find any solution. even on AEScripts 🙁

thank you !!! SO MUCH !
I was trying this way :

// myMaskFeather = newMask.property(“maskFeather”);
// myMaskFeather.setValue(15);

but it was always making errors… so thanks a lot and here’s my script
(coded with feet… but for a first script I’m happy) It’s a tool to transform 3D locators from maya and syntheyes in my case to a 2D_null, a 2D_solid with a mask or a 2D_patch… the 2D patch is used to replicate and offset a small portion of a footage to erase the tracked markers.. simple but so usefull for the project I’m working on…

I know there are a lot of improvments to be more powerfull :
mask size is in percent but if you set under 50% it will invert the mask, as it is based on the vertex position.

feel free to use it and improve it… (and share your feeedback) I think I will try to go further with my poor scripting skills. I will try to give the user the ability to bake the expression on the created objects position. And a second feature would be to translate it in french 🙂

Ok I solved the problem by putting a return; after ofsYfld.onChange = onOfsYChange;
and it well formatted in AfterEffects … maybe it’s the wrong way … but it works (I don’t know why :)… if you have a best way to do it I would be happy to know…

[Nicolas Elsig]

thank you so much … I will analyze this script and try to understand exactly what each line do.

Thank you for your help and the time you took to write this script

All the best
Nicolas
