Environment
- Minecraft: 1.20.1
- Mod loader: Forge 47.4.16
- Java: Azul Zulu 17.0.11
- OS: Windows 11 amd64
- VR mod: Vivecraft
1.20.1-1.3.13-forge
- VR runtime/device: SteamVR/OpenVR, Oculus Quest 3
- Affected mod: Gnetum
2.4.1
Summary
When Gnetum 2.4.1 is installed together with Vivecraft on Forge 1.20.1, the in-game HUD does not render in VR. The hotbar, health, hunger, thirst/status bars, Jade overlay, and Xaero minimap disappear. The HUD sometimes flashes for a single frame while switching screens or opening/closing menus, but it is not visible during normal gameplay.
Disabling Gnetum fixes the issue. After a modpack bisection, Gnetum was the only remaining mod that consistently reproduced the HUD disappearance.
Expected Behavior
The vanilla HUD and other HUD overlays should remain visible in Vivecraft VR, or Gnetum should detect Vivecraft/VR render passes and avoid redirecting/suppressing the HUD in a way that prevents Vivecraft from compositing it into the VR GUI/HUD render target.
Actual Behavior
With Gnetum enabled:
- Hotbar is not visible.
- Health/hunger/thirst/status bars are not visible.
- Jade and Xaero minimap overlays are not visible.
- HUD appears only briefly during screen/menu transitions.
- The game does not necessarily crash; this is a rendering/compositing issue.
With Gnetum disabled:
- Vivecraft HUD renders normally again.
- Other tested HUD/UI candidates can remain enabled.
Reproduction Notes
This was reproduced in a large Forge 1.20.1 modpack, then narrowed down by bisection:
- Start with the modpack where Vivecraft VR HUD is missing.
- Disable large groups of mods until the HUD becomes visible again.
- Restore the disabled mods in halves.
- Narrow the failing group to
ghosts-1.20.1-1.1.0.jar and gnetum-2.4.1.jar.
- Test
ghosts alone: HUD remains visible.
- Test
gnetum-2.4.1.jar: HUD disappears.
Current Vivecraft HUD-related config was checked:
"hideGUI": "false",
"shaderGUIRender": "BEFORE_TRANSLUCENT_SOLID",
"vrHudLockMode": "WRIST"
Gnetum config was left enabled during the failing test:
"enabled": {
"value": "ON"
},
"showHudFps": {
"value": "ON"
},
"numberOfPasses": 3,
"maxFps": 30,
"screenMaxFps": 30The config also contains mapped vanilla HUD elements such as:
minecraft:hotbarminecraft:experience_barminecraft:crosshairgnetum:minecraft_handgnetum:status_bar
Additional Context
Other suspected HUD/UI mods were tested and did not turn out to be the final cause, including ModernUI, FancyMenu, EclipticSeasons/SeasonHUD, MCFaceTracking, Xaero, Jade, ColorfulHearts, Oculus/Iris, and multiple render optimization mods. The issue specifically returned when Gnetum was restored.
If helpful, I can provide the full mod list and client logs, but there is no clear crash stacktrace because the failure is a HUD render issue rather than a startup crash.
