Calibration saving/loading isn't perfect (offset)
needs more information

Upon loading a saved FBT calibration, it won't be perfect and the hip tracker will often be noticeably offset (since that's the most obvious one).
To reproduce:
- Calibrate FBT, making sure your spine is straight
- Change world
- Check if spine is still straight
Might also work when changing avatar...
More likely than not, the spine won't be straight anymore (the hip tracking will be offset a couple cm to a side for example). Probably does this with every tracker as well.
I think not having the exact same pose when leaving the world and loading in might be a factor, but I didn't test that theory.

Hi Erimel, we're having some trouble reproducing this one on our end. Is there any other context/details you can add that might help us?

Hey Truce
Resetting the avatar while moving around seems to be a good way to trigger the issue (video attached)
Doing the same but without moving does seem to trigger it though (no video)
I assume there's some discrepancy happening somewhere in the loading if the trackers are not in the same position as when they were saved.
Maybe it could have something to do with the avatar's root position potentially not being the same as the hip's and that not being accounted for (if it's the case).
The intensity of the problem could also be FPS-dependant. I am currently running my Valve Index at 80hz, but I was running it at 90hz before; never above. The attached video is at a stable 80fps in my home world.
The offset is pretty much always going to my right as far as I can recall...
I use 3 Vive trackers, 80% tracker motion prediction and lock-all.
Attached video (Canny doesn't accept MP4s): https://files.catbox.moe/sdiylf.mp4
Attached is a picture of a before/after of the video with lines that are about straight (I tried). And yes, my head is hunched to the right, it's always light that...

Erimel: Thank you! I'll pass it along and see we can get a confirmed repro.
