Rotation to Opacity but ignoring the minus sign in the negative values
I am using this expression to link the opacity of a text layer to the y rotation or another layer
T = comp(“COMP_1”).layer(“Picture”).transform.yRotation;
[linear(T, 0, 70, 100, 0)]
The picture layer goes from 70 deg to 0 deg then from 0 deg to -70 deg and I want the opacity of my text layer to go from 0 to 100 and then from 100 to 0 as the picture layer rotates.
So basically what I’m asking is how do I get the expression to ignore the minus sign in the rotation values?
Thanks

This should work:
T = Math.abs(comp(“COMP_1”).layer(“Picture”).transform.yRotation);
[linear(T, 0, 70, 100, 0)]Dan
