It just doesnt work

[stoneychildson]

I've tried many times , it worked once a long time ago and then randomly stopped working forever , bepinex loads in the background but when the game loads it's just plain old gross normal subnautica VR . Im stumped , what do i do . I tried deleting everything , reinstalling and going through the whole process but same issue , what do i do

[karlheinz2k2]

Same here. Setup: Win10 + Quest 3 Headset

Have installed Bepines + SumbersedVR Tried a few times, did not work, normal movement with headset worked Then I added "-vrmode openvr" to the Subnautica icon in steam. Sumersed worked perfectly with the Qusest 3 Controllers. But since then it doesn't. Bepinex loads but have standard movement only (headset), the Quest 3 controllers do not work. Tried it with SteamLink and QuestLink. Nothing.

How to fix this?

[Okabintaro]

Can you post logs? Unfortunately I don't have a quest 3 to test myself with. The logs can be found in steamapps\common\Subnautica\BepInEx, when you open the local files by right clicking on the Subnautica in steam.

[lexicompendium]

I am using a Quest 2, not 3, but I have the same issue so I'm putting the logs here in case it helps. LogOutput.log

[Error :SubmersedVR] SubmersedVR only supports SteamVR! Make sure to add -vrmode openvr to your games advanded launch options when using an oculus headset.

[lexicompendium]

I have added that line to the advanced options, so I don’t know what else to do. The game launches to my oculus and I can play, just without motion controls.

[farmboy0]

Are you sure you extracted the plugin correctly? The folder SubmersedVR_0.1.6 shouldnt exist.

[farmboy0]

I am not sure BepInEx will load dlls directly from the plugins directory you might need to put the dll into a subdirectory.

[lexicompendium]

You're right that I had extracted it incorrectly, but fixing it didn't seem to work. I've attached the logs from that attempt. By putting it into a subdirectory, do you mean putting the submersedvr.dll into one of the folders within the plugins forlder? and if so, do you know which one? LogOutput2.log

[Okabintaro]

From your latest log:

[Error :SubmersedVR] SubmersedVR only supports SteamVR! Make sure to add -vrmode openvr to your games advanded launch options when using an oculus headset.

Make sure to start the game from steamvr and not the oculus dashboard.

[lexicompendium]

I have been doing that, launching the game through steamvr on my desktop while the quest is linked. My exact process is that I set up the Quest Link, open Steam on computer, launch Subnautica in VR mode (with the -vrmode openvr script in the launch options), and then it automatically is broadcast to my oculus but without motion controls. Is there anything in that process I am doing wrong? Thank you all so much for your help, by the way, I really appreciate it

[Okabintaro]

Can you try opening steamvr inside the oculus dashboard and then starting subnautica from within steamvr there. Like don't use steam on the desktop but inside VR. There should be an application for Steamvr in the oculus link dashboard. If not then you might have to install steamvr first.

[yunyuyuan]

@Okabintaro I had the same issue, and I just tried your method above. It works like a charm!

[Plat12]

@Okabintaro I have the same issue, I'm playing on a quest 3 and launching the game trough quest link using steamvr, I have the -vrmode openvr launch options selected yet bepinex outputs the following on bootup: [Warning:SubmersedVR] Game was not started in VR. Don't load and apply SubmersedVR patches. Regardless of how the game is started. I followed your advice to launch the game from within quest link but it doesn't function still.

Can you try starting SteamVR first in Quest Link and then from within SteamVR on the dashboard start Subnautica. That should guarantee the game being started in VR.

[Plat12]

That's what I've been doing unfortunately:

Connect the headset Activate Quest link through the headset Boot up steamvr from the Qlink Boot up subnautica from Steamvr

it still doesn't detect the game being in VR

That's weird. Only other thing I can imagine is that you played Subnautica on PC before and set it to always start in desktop mode. Normally steam will ask you if you wanna play in VR or not. But if you chose Desktop mode and remembered that using the checkbox maybe it's stuck in there.

Maybe try starting it from the desktop steam client while SteamVR is running and make sure it's doing the VR mode? I am not sure how you would clear the default desktop mode though.

[Plat12]

Nope, never played before on this account. Could I somehow edit the .dll to not run those checks and apply the patches regardless? Could that fix it?

[Okabintaro]

Just to be sure. You put the launch option in the Subnautica Game and not in SteamVR?

I am out of ideas. I would maybe try reinstalling the game and see if you can run the game in SteamVR without the mod first.

[Plat12]

yes, the launch option is in the Subnautica game, i already did a full reinstall :(. Is the editing of the .dll unfeasible?

[Okabintaro]

The mod only works if it's running the SteamVR runtime. Removing the check would break it even more I am afraid. You can try building the mod without it but it's there for a reason.

You could try another streamer for the quest like ALVR or Virtual Desktop which always uses SteamVR but I am not sure why it's not working for you.

[Okabintaro]

Oh, I heard steam link is pretty good too and super easy to setup.

[Plat12]

i have ALVR. lemme try it

[Plat12]

Still doesn't function with ALVR

[Okabintaro]

What does it do? If it doesn't start in VR at all your SteamVR setup seems to be broken.

[Plat12]

It starts in VR, the main menu loads and the headset works but the controllers don't, and the time i managed to click the required buttons to start a new save from the main menu, the controllers still aren't detected in-game

[Plat12]

it's exactly the same as with Qlink

[Okabintaro]

And you get the same log line with the game not being started in VR? The only way it could work is with SteamVR with alvr, so I am confused. I can build you a version without the check tonight but I am not sure it's gonna help.

[Plat12]

Yep, same log line. The check-less version would be really helpful :)

[Okabintaro]

SubmersedVR.zip There you go, it's just the DLL but I removed the VR and runtime checks.

[Plat12]

Thank you! Unfortunately it still doesn't work, here's the error:

Yeah I am afraid it would break. Are you using some old version of Subnautica? Only most recent version will work.

[Plat12]

v72550

[Plat12]

@Okabintaro issue is completely resolved, i updated the game to the march 2023 version and it works flawlessly, thanks!!!
