createPath in 3D space.

[Dan Ebberts]

I haven’t had a chance to test this, so there may be typos, but something like this I think:

a = [];
for ( i = 1; i <= thisComp.numLayers; i++){
  L = thisComp.layer(i);
  if (L.name.substr(0,4) == "smet"){
    a.push(fromComp(L.toComp(L.anchorPoint)));
  }
}
createPath(a,[],[],false)

Push error. I don’t even know where the syntax might be wrong.

[Dan Ebberts]

The 5th line should be:

a.push(fromComp(L.toComp(L.anchorPoint)));

[Smet Kira]

it is not clear what points he is missing.

[Dan Ebberts]

I think you’ll get that message if you’ve made the line layer 3D.

[Smet Kira]

i have 3d layers. I thought everything would be easier and regardless of 2d or 3d, the position will pick up equally well

[Dan Ebberts]

It should work fine with the smet layers as 3D, but not the line layer.

[Smet Kira]

Yes it works. But the original goal was that the line should also be in 3D and the depth of field on it would be different depending on the distance from the camera. This can be done?

[Dan Ebberts]

Well, you can’t have a 3D path, so the best you could do is to break it into a bunch of segments, with one path layer required for each connection between 3D layers. Then you could make each path layer 3D (but the path itself would still be 2D), but then you have to worry about positioning it in world 3D space and orienting is so that it connects between the 3D layers and also presents itself to the camera in a way that maximizes its visibility (so that it’s not edge-on to the camera). Lots of work…

Understood. Thank you for the tip and for your help, for your effort and time!
