  1/x expression doesnt work

  Posted by Joscar Diaz on March 9, 2022 at 7:06 pm

  Hello, Im doing a scale expression to compensate the scale on other object, for example when Null1 is at 50%, the Null2 must be 200%. The same say if Null 1 is 400%, Null 2 must be 25%

  Im going for a (10000/x) to get that number

  In After Effects im using this expression, but im getting error:

  10000/thisComp.layer(“Null 1”).transform.scale

  if I use a division (/) symbol I always get an error, but if I Plus or Multiply works perfectly.

  There is another way to write this? Thanks

  If your scale is uniform, just do this:

  10000/thisComp.layer(“Null 1”).transform.scale[0]
  
  Scale is a 2D array and it contains x and y value.

  Hi Tomas, Thanks!, I added the [0] at the end and I got a different error message
  error: expression result must be on dimension 2, not 1

  
  

  SO I updated it like this and worked

  [10000,10000]/thisComp.layer(“Null_1”).transform.scale[0]

  And if the scale isn’t uniform, then this would work:

  s=thisComp.layer(“Null_1”).transform.scale;
  [10000/s[0], 10000/s[1]];

  Thanks Filip! That one also worked
