link stroke width to camera position
Looking for help with linking stroke width to camera position z depth. Basically, looking to keep all my outline strokes the same size, even when object fly toward camera. Currently, when object flies towards and past camera, stroke size increases (as it should) but I need to keep all strokes the same for cartoon effect.
Thanks in advance for all responses!

Something like this should help:
nominalDist = 400;
d = length (thisComp.layer(“Camera 1”).toWorld([0,0,0]),toWorld(anchorPoint));
value*(d/nominalDist)Set nominalDist to the distance where you want the stroke width to be the value you have it set to.

Works like a charm!! Thanks!!

I am trying to achieve the same effect with the stroke linked to the camera to keep the stroke width consistent.
On what layer and what attribute do I put the expression on?
Thanks for any assistance you can offer.

You would apply that expression to the stroke width property.

Thanks for your help Dan.

I said it before, I’ll say it again:
Dan, you are the MAN! -
Hi Dan,
I came across this thread today, and your expression works like a charm. I’m curious if there’s a way to achieve a similar effect, when there is no camera in the scene. If the line itself moves in Z space (not the camera) could the stroke remain constant?
Thanks,

You could try using something like this to simulate a camera:
nominalDist = 400;
w = thisComp.width * thisComp.pixelAspect;
z = (w/2)/Math.tan(degreesToRadians(19.8));
C = [thisComp.width/2,thisComp.height/2,-z];
d = length (C,toWorld(anchorPoint));
value*(d/nominalDist)
