You can send Steam Frame eye-openness data to Climbey over OSC when playing through streaming, provided SteamVR is on Beta 2.18.2 or later and SteamOS is 0.4.3 or later. Climbey added OSC eye-openness support in its October 2, 2026 update. The official release notes establish this route, but do not publish the specific OSC addresses or a click-by-click setup procedure.
What you need for the streamed OSC route
- Steam Frame and streaming: Valve says SteamVR exposes Steam Frame eye-openness information via OSC when streaming.
- SteamVR Beta 2.18.2 or later: Valve announced the feature in its October 1, 2026 SteamVR Beta 2.18.2 notes.
- SteamOS 0.4.3 or later: Valve lists this as a requirement. At the time of the announcement, SteamOS 0.4.3 was on the OS Beta branch, so do not assume the announcement establishes stable-channel availability.
- Climbey with OSC openness support: Climbey added this in its October 2, 2026 update.
In short, the documented data path is Steam Frame → SteamVR while streaming → OSC → Climbey. The SteamVR and Climbey notes confirm the sender and receiver support, but do not specify an OSC address mapping or a Climbey-specific setup setting.
How to set up the documented path
- Check the software versions. Confirm SteamVR is Beta 2.18.2 or later and SteamOS is 0.4.3 or later. The SteamVR beta announcement identifies the SteamOS minimum.
- Run Climbey through streaming. The SteamVR feature is described as exposing eye openness when streaming from Steam Frame; the release notes do not confirm an equivalent route when Climbey runs natively on the headset.
- Use the current Climbey build that includes its October 2, 2026 OSC eye-openness update. The update announces receiver support, but does not provide a specific menu path or configuration step.
- Verify OSC reception using the current SteamVR and Climbey documentation or interface. The cited release notes do not state an OSC sharing toggle, address path, or other exact setting, so there is no source-backed menu instruction to give here.
Streaming and native headset use are different cases
| How Climbey runs | What the official notes establish |
|---|---|
| Streamed from Steam Frame | SteamVR Beta 2.18.2 exposes eye-openness information via OSC while streaming, with SteamOS 0.4.3 or higher; Climbey added OSC eye-openness support in its October 2, 2026 update. |
| Natively on Steam Frame | The cited notes do not confirm that the same OSC handoff works when Climbey runs natively on the headset. |
Valve’s Steamworks documentation describes its current eye-tracking support as using the XR_EXT_eye_gaze_interaction OpenXR extension. That is a documented eye-gaze interface; it is not, by itself, confirmation of Climbey’s OSC setup. The newer streaming-over-OSC statement comes from SteamVR’s beta notes.
Why older Climbey instructions may not match
Climbey’s December 24, 2025 update said multiplayer eye tracking required streaming through Steam Link and that Steam Frame did not then broadcast OSC data itself. The October 2026 SteamVR and Climbey updates are later changes, so the 2025 limitation should not be treated as the current setup description.

Steam Link notes from 2024 discuss eye-gaze passthrough through OpenXR and a renamed eye-tracking sharing setting. Those notes describe an earlier Steam Link workflow, not the newer Steam Frame eye-openness OSC feature. Do not assume their setting name or menu path applies to the current route.
What to check if Climbey receives no openness data
- Confirm that Climbey is being streamed from Steam Frame, rather than running natively on the headset.
- Check the SteamOS and SteamVR versions against the minimums in Valve’s October 1, 2026 beta announcement.
- Confirm Climbey includes its October 2, 2026 update or a later build.
- Look for current, version-matched SteamVR or Climbey instructions for OSC sharing and address configuration. The cited release notes do not state the toggle name or OSC paths, so guessing at either can lead to a misleading setup.
Valve also said in the October 1, 2026 beta notes that OpenVR SDK availability for eye openness was planned for an upcoming release. That is a forward-looking statement in those notes, not confirmation that the SDK support was already available.
