Camera focal length animation not importing
Open, Needs TriagePublic

Short description of error

When importing camera in FBX or ABC file (exported from Nuke), the animation of focal length is not importing. It's being set to a constant value according to frame 1. Other values are imported correctly.
If I reimport to Nuke, the focal length is correctly animated.

Camera files attached.


To Do

I cannot speak for FBX files, but in the case of Alembic files this is not a bug, but a limitation of the current implementation (however I used to work on a patch for supporting such features D2324).

I can confirm that is a known limitation for FBX.
According to documentation, Focal length is not supported, yet.

It is not the first time that feature request is made to be able to work with Nuke.
I let @Bastien Montagne (mont29) close this report or attach it to a duplicate.

Implemented import & export of camera focal length in FBX now, so will re-assign to @Sybren A. Stüvel (sybren) for the Alembic part of it…
