Automation Blocks - Get property value that have an expression

Hello!

I'm trying to get a value from the Position property that have an expression which is modifing the original value to a new one, but whenever I use the Get Attribute type "Value" block, it gets the raw value instead the new one with the expression.

I even tried using a custom script block with the ".valueAtTime(currentTime, true)" to get value with expression but still no good.

Is there a way to actually get the current value of the property?

 

Thank you!

Actually, Automation Blocks returns the post expression value. I just did a quick check and on my machine it works as expected:

Here the pre-expression value is [50,50] and the expression adds 100 to both x and y.

Maybe you are accidentally retrieving the value of a wrong property or some other bug in your code?

      I think "true" gives you the pre-expression value. Try "false".

      Yea, I tried both. Each returns a different value, but neither are correct.
