3D Rig View - Camera FOV, Focal Length Display, and Lens Representation¶

CONFIRMED FLAIR 7

Summary¶

To make 3D Rig View represent camera focal length/FOV, Flair needs both camera format/sensor data and the Rig View camera FOV calculation enabled. The Zoom axis must also be active/on so the viewer has a focal length value to use.

Symptoms¶

3D Rig View camera perspective does not match expected lens/FOV
Lens/focal length representation does not appear to change
Changing lens profile does not update viewer
Viewer is good enough for previs only after extra settings are enabled

Stable ID¶

ISSUE-VIEW-001

First Reported¶

2025-10-17 - question about whether 3D Rig View camera perspective shows focal length.

Additional Reports¶

2026-05-12 - user confirmed the working setup steps.

Software Environment¶

Flair 7. Classic rig model workflows may differ.

To see lens representation in 3D Rig View:

Set camera format with sensor information in the Flair camera / film-back setup for the job.
Open 3D Rig View -> Camera Settings.
Enable Calculate Camera FOV.
Select camera view.
Turn on the Zoom axis.
Set the focal length needed.

Changing lens profiles alone is not enough if Zoom is turned off.

2025-10-17 20:12 - Timothy Heys Cerchio: Flair is suggesting that in Setup - Axes - Zoom the (second line) Display Scale should be the same value of Internal Scale (next box along)
2025-10-17 21:29 - Timothy Heys Cerchio: After a bit of testing on Flair 7, I realise the Flatten option is NOT available there... 🤷🏼‍♂️
2025-10-17 21:36 - ~ Ahmad Rifa' ie: Hi everyone, is the 3D rig view, camera perspective, showing the focal length of the lens setup used?
2025-10-17 21:52 - ~ Julian Hermannsen: What I meant in flair classic is: Add points and then it's one of the reset functions for the tangents of the points. Holding down another button like shift or Ctrl while doing it if I remember correctly. This is useful because it's impossible otherwise to get the tangents of the 2 middle points for the stop exactly flat
2026-05-12 11:04 - ~ Marcin Biegunajtys: Ok, so here is an update: if you want to see a representation of the lens, you not only need to have camera format setup with the sensor info, then inside the 3d rig view you need to click on camera settings and make sure „calculate camera FOV” is on. The rest is irrelevant in the viewer, so just select view: camera and then make sure you turn on zoom axis, and set the focal length you need. I was clicking away and changing my lenses and expected the viewer to snap to the focal length, but I...
