3D Track Matte problem

[Anders Hattne]

How Curious!
Are the layers correctly placed in 3d space?

If nothing else, a work around would be to pre-compose the needle with its track matte and link the nested animations with expressions. That way you only have to take care of one layer in 3d space..

They seem to be all lined up correctly. I tried shifting them back and forth on the z-axis and rearranging layers, but still didn’t work.

Your work around fixed the problem, so thanks a bunch!

Only thing, those meters were parented to another layer and now the precomp isn’t lining up correctly when the parented layer moves. Also the precomp needs to have “continuous rasterize” on and that seems to mess up it’s position when I turn that on and off.

But now I know, when in doubt, precomp.

In this post Dan Ebberts helped me out with the position of a precomped object. I don’t understand how he understood my question but his answer works! ..although that one might be tricky too:

L1 = comp(“Crane”).layer(“Hook”);
P = L1.toWorld(L1.anchorPoint);
L2 = thisComp.layer(“Crane”);
L2.toWorld(P);

crane would be the precomped layer, hook the object therein.
I’m still struggling, but it works!

Cool! Thanks for all the help, you rock!

You might be have Fast Previews set to “Fast Draft”. I can see that it is set to something in your image.
If you set it to “Off (Final Quality)” or “Adaptive” your comp may look as expected.
I suffered a similar problem with track mattes on a 3d layer and found another user on this forum that said the problem fixed itself in the final render, then I tried my comp as a final render and my objects appeared in the right order. So then I had a light bulb go off in my head and tried the setting above and it fixed my problem.

Didn’t take time to read all the answers, but if you turn off raytrace and choose classic rendering in your advanced comp settings, then it will appear again.
