FBX Camera Import into Sequencer - Scale Does Not Apply to Scene-Dependent Attributes (e.g., Focus Distance)

When importing an FBX camera into a Level Sequence via the FBX Import dialog, we rely heavily on the

Import Uniform Scale

and

Convert Scene Unit

options for DCC interoperability. These settings should ensure that the spatial scale of the camera and its properties match our original scene from tools like Maya.

Currently, when applying a scale (e.g., Import Uniform Scale = 10.0), only the camera actor’s transform (location, rotation, scale) is affected. Scene-dependent camera attributes — most critically Manual Focus Distance — are not scaled accordingly.

This leads to mismatches in focus distance in Sequencer shots when compared to the original DCC. This is especially problematic in virtual production and cinematics pipelines where accurate focus pulling is crucial.

Expected Behavior:

If

Import Uniform Scale

or

Convert Scene Unit

is applied during FBX import, we expect all scene-dependent properties — such as Manual Focus Distance — to be automatically scaled to match the imported world scale. Properties like focal length or aperture (which are intrinsic to the lens) should remain unchanged, but positional/distance-based properties should scale.

Steps to Reproduce

In a DCC (e.g., Maya), create a camera with a custom focus distance animation

Export as FBX

In Unreal Engine 5:

• Open a Level Sequence.
• Create a Camera

• Import the FBX into the camera (right-click the camera and Import...).

• Set the

  Import Uniform Scale

  = 10, or whatever would be the unit conversion scale.

• Optionally enable

  Convert Scene Unit, apparently it does not make a difference

  .

Observe that the camera actor Transform scales correctly.

Check

Manual Focus Distance

value: it remains as in the FBX, unscaled, which no longer matches the spatially accurate focal point in world space.
