  Scalar property Error

  Posted by kees mansvelder on February 15, 2021 at 3:47 pm

  Hi!

  I am trying to make a hover reveal effect. But it keeps asking for a scalar property.

  I have this expression on the opacity layer of the hover.

  a = thisComp.layer(“Null 1”).transform.anchorPoint;

  s = thisLayer;

  f = s.sampleImage(a,[.1,.1])[3];

  linear(a,0,1,0,100);

  the error I get is as follows

  error: argument 1 of linear() has to be scalar

  What does this mean and how do I solve it?
