Auto Orient not working with expression.
I want an arrowhead to follow a path. For which I am using this expression on its position property.
t=thisComp.layer(index+1).content(“Path”).content(“Path 1”).path;
l=thisComp.layer(index+1).content(“Path”).content(“Trim Paths 1”).end;t.pointOnPath(percentage = l/100, t = time)
Everything is working fine except the auto-Orient. As soon as the animation completes it stops working. It only rotates the layer if its position velocity is > 0. Otherwise, it sets the layer back to the original.

Hi Ranveer, you could use the tangentOnPath function, like Dan discribed here:

This might have some issues with a trim path end value of exactly 0, but you could add an if statement to set the value to something like 0.1 if the end is exactly at 0 🙂
Auto Orient expression to use for path layer? (Don’t need built in AE option)

It doesn’t matter what’s the value of my end or starting point is. It always glitches at the very beginning and end. It’s more like if the position velocity is more than 0 it will Auto orient it otherwise it won’t.

Yeaht thats the problem with auto orient, thats why you should use the expression I linked instead
