Yeah, it works like that.

But the arrow head is then flat against the null.

I need to add some extra rotation to get the ‘sharp end’ pointing in the direction of travel.

As soon as I add some extra rotation like this…

thisComp.layer(“Null 2”).transform.orientation[0]+90

it gets screwy!

Ah, Gotcha!

It works!

except that it doesn’t!

I think because 3D Stroke doesn’t have an ‘orientation’ parameter, and I’m doing individual links from the 3 rotation parameters, its getting cocked up because of the difference between rotation and orientation (which is something I’ve yet to fathom)

Sorry to be a pain in the arse Dan – but any other ideas?

I may be being dumb here (its possible!)

But how does that differ from what I’ve already got?

If I create a new Null (Null 2) with a motion path and add Auto Orient, and add your expression to the orientation parameter; won’t I just have the same thing as Null 1?

Hey Dan,

Yeah, I am applying it to the arrowhead, but its a 3D Stroke object.

So I need to pick whip the nulls orientation to the transformations within 3D Stroke effect rather than the layer transformations.

Here’s a link to the reduced project…

Does this make sense?
