Maybe the offsets are different for Index and other lighthouse HMDs. --- End quote --- Actually I remembered that my vive had a problem, the hdmi part of the 3 in 1 long cable isn't working. I can get the headset to work if I snake a hdmi cable in there so I know it's just the cable. But I remembered that I had a Pimax HMD and that also works on lighthouse so I've been using it. I don't really think the headset should matter that much as the values should still come out the same but I could be wrong. But the room setup may affect it, are you using a room setup or like a sitting mode or something else? There is a variable I'm using that is for standing and the other options are for sitting or raw and uncalibrated. I think I thought standing would work for a normal room setup so chose that. --- Quote from: Toasty833 on May 05, 2024, 01:50:09 pm ---When I save coords, they replay as upside down and in the floor. --- End quote --- If you save the coords, then replay them and then save them again while replaying. And then replay that save, is it still printing out the same coords on is it changing around? Probably best to open two cmd prompts and run the commands so you can see all the outputs. Also you can use OVIE offsets to try to do the correction, I found you can change the numbers by typing them in so that saves pressing the + / - buttons |

OVIE works fine for remapping my tracker position, so who knows. --- Quote from: greymatr on May 05, 2024, 02:16:37 pm ---If you save the coords, then replay them and then save them again while replaying.

If I manually adjust the coords they change too, by saving with my headset inverted I got kind of close and have been manually dialing it in by adjusting and comparing. --- Quote from: greymatr on May 05, 2024, 02:16:37 pm ---Also you can use OVIE offsets to try to do the correction, I found you can change the numbers by typing them in so that saves pressing the + / - buttons --- End quote --- I worry that this will have the same offset issue so I haven't tried it yet, maybe I will for fine tuning when I get a good alignment. It's also hard to get a good view of when my headset is so far away from the actual playspace, can't get the controllers to hit the buttons a mile in the air. Edit: Tried it out by adjusting yaw, but it sent the new saved coords off into the stratosphere again. Manually adjusting the vrdeskHMD pose is what works for me, so I'm going to stick with it. Didn't know about the desktop mode though, I might try that out in the future. |

If you go into: C:\Program Files\OpenVR-InputEmulator there is a batch file called startdesktopmode.bat That will bring OVIE up on the desktop. That is how I've been using it --- Quote from: Toasty833 on May 05, 2024, 01:50:09 pm ---Edit 2: Tried restarting SteamVR, and it seems like the pose data is back to the initial set so I can keep working on my calibration. It might've changed slightly, I'll see if it stays consistent through resets and over play sessions. As long as it's the same on boot every time it should work fine though. --- End quote --- I saw this edit too, so I hope that it will work. Let me know how you go |

So I did some more testing today. First run, all the offsets were off again, second they were as before. It seems that when my headset loses tracking it can switch to a different offset pattern. The first offset is roughly upside down and 3-4 feet higher. The second one is a 2-3 feet higher turned 90 degrees right, with the headset also being turned about 90 degrees right. These both affect the replays, but cycling the HMD tends to put it back on the first offset. I tried updating to the latest steamVR beta, no change. I tried roomscale rather than standing room only, no change. I tried saving poses from my tracker instead by trying to save a different device number, but this always returned the same value. I tried uninstalling other VR overlays and such, didn't help. I went back to manual adjustment, this time with the help of OVIE on the desktop. I can't save the offset over the replay without it just compounding the existing offset bug, but I can just save it as a profile in OVIE and then load up the replay and apply the profile to fine tune it. Which also lets me adjust on the fly using VR view, which is useful. As of right now I've got it in the general ballpark, just needs a lot of fine tuning, which OVIE isn't great at. |

I will try to get my Vive headset out later today and see if I can get it working and then see if I can replicate the issues. The reason it doesn't work with a different device number is because it uses a OpenVR call that is specific to the HMD but this could also be part of the problem if the Vive works differently to the Pimax. I'll have to test that and may have to rewrite it. Either way though, the replay function is only working to replay on the HMD at the moment. That could possibly be changed but seemed like we only needed to replay the HMD. |
