Impossible to use the chair_device when physics is enabled

Summary

If physics is enabled in the project, the chair_device cannot be used. The player cannot interact with the chair, so sitting on it is impossible. Even through Verse, the Seat method cannot be used to force the player to sit.

I’m still having this issue…is there any fix planned? Thanks.

I can confirm the problem still exists, and it’s been almost 6 months and the problem still hasn’t been fixed.

FORT-963421 has been ‘Closed’. This issue won’t be fixed—please see examples of why this may be the case.

Is there a fix? I want to use chair device with physics in my project.

Hi @Rufhig and all

When using the UEFN Feature Example

Verse Stand-Up Comedy Club Template in Unreal Editor for Fortnite | Fortnite Documentation | Epic Developer Community

the Chair Device documentation

Using Chair Devices in Fortnite Creative | Fortnite Documentation | Epic Developer Community

Enable Physics in Example project

  1. Add Physics Component: Select the prop in your viewport. In the Details panel, click + Add, and search for and select Fort Physics.

  2. Configure Simulation: Within the Fort Physics component settings, you can:

    • Enable/Disable Simulation: Toggles physics on or off.

    • Simulate Physics: Check this box to allow the object to fall or move.

    • Override Mass: Adjust the weight of the object in kilograms.

    • Gravity: Toggle gravity on or off for the object.

    • Collision: Ensure the object has “Simple Collision” enabled to interact properly

  3. When you run the example the chair_device works with Physics is enabled

  4. You can sit on a chair and press key to exit

This is why there is no bug to fix/correct as the UEFN Example as described in documentation works

Originally when April 2025 the thread was started the Physics was beta meaning THAT TIME it would not work as it was BETA Now its production chair/physics in the example now works
