Just to clear up a few things:
1. The skating can be heavily mitigated by our anti-skating option, which can be dialed up or down depending on personal preference. The better your skeleton is, the less you will need this.
2. The autobone never needs to be done after you get your proportions correct (unless your are growing). The 4 moves only need to be done once in the thirty second window.
3. Joycons are really, really bad. Try not to judge slimevr on its tracking fidelity after using just joycons. Its the bottom of the barrel in terms of IMU performance.
4. 5 slimes are needed, minimum, to track lower body. It wont work with only three (for maths reasons)
5. We have regular events if you want to come ask questions or get your tracking ironed out. If it seems like a big scary thing, just come lean on the community a bit! We love new people <3

(1/2) for anyone else who noticed the floatyness in clips like 12:19, that's to do with head/waist lock settings in Vrchat 90% of the time, i had that issue before and fixed it by changing the headlock/waistlock settings, if your slimes have high latency it would be displayed in the server, and would be more likely to present as the entire system going out of sync with itself, like half a leg moving before the other half rarther than the entire system seeming to lag behind together as one, love yall :)

I have slimes and this is a pretty good overview!
I will say though: once you get your body measurements correctly you never need to do the little hula dance ever again. When your trackers move position you can just do a full reset and mounting reset which are consistent and take about 20 seconds combined. So your extra calibrations after you got it right werent even needed!

[deadlokIV]

Aw yeee, the best bit was when Thrill was like "it's slimin' time" and the slime trackers slimed the best and most expressive they've ever slimed

[YoBoyNeptune]

The slime knows where it is at all times. It knows this because it knows where it isn't. By subtracting...

[Vanguard]

The calibration process looks like the Club Penguin dance

[epicthief]

Still surprised that Meta doesn't have its own IMU trackers, it would instantly solve all their leg problems

[WestonHawk]

You don't need to redo autobone or proportions ever again once your body proportions are correct, even if you mount them differently! As long as they are on the same part of your body, you only ever need to do the full and mounting reset at the very start, which takes all of 20 seconds while standing. Then when you notice drift, which takes at least 20-30 minutes with a lot of physical movement, you do the yaw/fast resets which is done in like 3 seconds. And when you do the yaw/fast reset, you do not need to stand up in a t-pose or recalibate your VRChat avatar tracking! You can do it while standing, sitting, or laying down, as long as your torso, arms, and legs, are facing the same direction as your HMD.

The Wii controllers used IMU based tracking, and there is an IR camera in each controller that is used to re-calibrate the controller position using the sensor bar as a fixed reference point. The distance between the lights and the angle of them give the Wii remote the info it needs to find its position. We could probably do something similar with a camera looking towards the slime trackers to re-home them when they come into view to automate the calibration process.

oh god that where you plug it in THEN turn it on.... you've just saved my life.... I've been struggling for days since I moved *sobbing*

[exentric]

I’m an XR developer and XR/IT support agent. Seeing you admit, your struggle really resonated with me and make me feel a little bit better about when I get a little “five headed “. I’ve never heard that term before.😂🎉 this looks like a great solution and I’m glad that you’re sharing it with us. Thank you so much.

[thebutlah]

You don't need to do the autobone/automatic proportions dance each playsession, because people's body proportions don't change. Only the automatic mounting calibration needs to be run each time, which only takes a second (the one where you squat).

So no hula dance necessary, once you get your proportions down to your satisfaction :)

[Jinxxedvrc]

I've been using SlimeVR (via phones) for about 2 years now, and it's been amazing! There are some downsides to it, like how often I have to recalibrate, but overall, I love it! Thanks for the new video, Thrill!

[JimmyNuisance]

If the 16 dollar chinese trackers actually work fairly well, it's going to take VR chat into the future overnight.

[ainedroid]

Yippee the slime revisit! Ordered mine during the initial crowdfunding campaign and I’m so excited for when mine finally ship home. I’ll finally be able to join my full body friends in VRC and stare at a mirror all evening lmao

[ErukanuSenpai]

I ordered Slime VR (7+3) in March '22
Original Shipping date was the end of August' 23
First delay to end of September '23
Second delay to November' 23
And now with the last post update they got delayed to the end of December '23

I am a very patient person, but if it gets delayed one more time, I'll cancel the order...
Yeah, that my experience with Slime VR so far 😢

[ZRockVR]

Awesome video on an incredible technology! Great editing and presentation.

SlimeVR has improved dramatically since the last video you did on it, for sure. There's things regarding setup and autobone that still need to be tweaked (autobone can be just wiggling around as long as the heels are planted according to the dev who made it, and animations will be added for simplicity), for sure, but overall it's way better than back then - that flashback sequence made me laugh, as well as the Level 99 Autobone bit (I got assigned that role in the discord server!)

This is really giving me a nudge on showing all the tips and tricks I know about SlimeVR, so thanks for that - I really want people to have the best experience they can with these!

Much love to both you and PHIA!

[lyonsdwyer]

like any other full body tracking method, it’s a bit wonky, but I can’t lie. The open source nature of it is insanely cool

[LazySquib]

i have close to 7k hours in VR but i could never justify buying trackers and everything just for FBT (ive only used oculus headsets), this gets me very excited for the future of FBT im glad you covered the good and the bad.
