VRChat
Full Body Tracker Question
Im looking to get full body trackers (waist + both legs) but it seems expensive so i thought I might get only the waist trackers, see how that goes then dish out and get the 2 leg ones. Is there any obvious flaw with this (like does it work with only waist and missing the legs, will everything still work?).

Or might it be better to get the 2 feet ones first. Will it also work with 2 feet but no waist tracker. I thought this might glitch avatars.

that is a very viable option. Who knew it would be cheaper to hump things rather an kick them. I was worried having feet tracking might glitch out avatars as they have no idea where the hips would be

Foot trackers will not work in vrchat without the waist tracker (it needs the waist for the IK solution to move the legs correctly), so I'd recommend getting the waist tracker first.

Tundra will be releasing their trackers hopefully soon. Look it up.
It was said that it is cheaper, too.

I got FBT and hip only is perfectly fine. Hip only is actually VERY stable and is useable with nearly ANY avatar. I haven't found an avatar yet that breaks with hip only.

Feet simply dont work by themselves though. They 100% requires the full deal to function and if you attempt feet without a hip 1 foot will become your "hip".

2, 3, 4, and 6 point tracking is all VRC supports.

2, head and 1 hand.
3, head and both hands
4, head/hands/hip
6, full FBT with head/hands/hip/feet.

When you get FBT though. Expect a LOT of avatars to break. The majority of avatars do NOT support FBT and those that do are often a bit jank from scaling being slightly off.

It's worth securing a main avatar, maybe a custom job, before getting FBT

Using OVR Advanced Settings can help a lot with that. You just change your in game height to match your trackers, then use OVR to move your play space up and down to match the floor. I don't use a large variety avatars, but I have yet to find one that doesn't work with FTB. Probably just super disproportionate ones with long/short legs/arms, or quadrupeds would be incompatible.
It also fixed the issue of my IRL floor not lining up with the in game one. Its free on steam so I highly recommend it, even if you don't use FBT.

Agree that OVR is a must. OVR Advanced Settings (the free one) is great overall for having an overlay that shows the center of your play space and how much you turned that session. Prevents a LOT of wall hits and twisted cables.

OVR Toolkit may cost like $10-20. But it gives you nearly perfect access to your desktop in any game. Much better than Steam's overlay and does so much more. Having a watch overlay alone is great for a clock, battery charges, music player, and PC performance.

But it hasn't helped with my FBT problems. Sinking or floating it helps. But if FBT breaks it destroys the avatar for me. Mostly by contorting the model into a twisted mess, compressed dark matter, or tilted meth addict.

When FBT works, it's great. But getting it to work is a ♥♥♥♥♥! One reason why most everything uses the same 5 base models and custom stuff is so rare.

To use full body tracking you need 3 vive trackers. Vive trackers do not represent a single part of the body as they are setup to a part of the body.

Costs:
HTC Vive Tracker x3 = $297.00
Rebuff Reality Trackbelt + Trackstrap x2 = $69.99
Tracker Powerbank x3 = $59.97
Total = $426.96

Yes, FBT is expensive.. The question simply is, is it worth it for you? For me, the answer is yes. especially in the cases of when I'm in VR Chat and I'm playing on desktop for whatever reason and someone wants to talk down to me and they don't have FBT. I am quick to shut someone down, and it's fun and funny. I love the experience and the freedom, even moreso with the powerbanks. Hearing someone complain about their trackers dying just makes me laugh.

You can use a single tracker and get your waist setup just fine, but you won't have your legs functional and frankly the difference in having just VR, VR with waist tracking and VR with FBT is intense. VR alone is amazing, VR with waist tracking is an unfulfilling medium. VR with FBT, it's like flipping the switch finally. You see and feel in a different way, I'd compare it to someone who's been wheelchair bound for life suddenly able to walk. You feel the world around you no longer disconnected, no separations to be made.

Optional pieces for FBT would be trackstraps, belts and powerbanks. From personal experience, you can get by using zipties to clothing or even string. Though these can prove to be a hassle at times, if you're really active or simply fidget too much you can end up messing your tracking up. The power banks though I feel are an actual necessity to have, unless you're not extremely active in VR, by extremely I mean you spend at a minimum of 7+ hours a day in VR.

Power banks: Super amazing, the fact you can charge your trackers and not be tethered to some power bank you have and long cords that can trip or injure you, or even worse get pulled out, broken off in the trackers.. Or just not charge because you didn't notice you pulled one out. Having some 2-3 inch cord that just plugs right in and gets you the juice you need is amazing. The fact they extend the life of your trackers to from what I get is usually a total of 9 hours of FBT without needing to charge is amazing. Keep in mind if you want to buy the straps and not the power banks if you change your mind, go for the straps with the power banks already attached to the straps, less wiggle = better tracking.

Thanks for your great reply, ive decided to get all 3 at once, but instead make it the new tundra trackers which will be slightly cheaper but mainly have double the battery life of the vive ones. Gotta wait a couple months tho D:

I've only had FBT for a few days now, the only real issue I have had was when my trackers got mixed up and it thought my left hand was my waist, and my left foot was my left hand. I just restarted steam VR and it fixed itself.
Your problem could be from a number of reasons, both on the software and hardware side, so its difficult to tell where to look to fix it.

As happy as everyone is with the idea of the tundra trackers, I think some fundamentals are lost.

1. Battery life, unknown.
2. Smaller and uneven surface. (possibly more likely to get interference during certain motions, sitting, kicking, bending over, etc.)
3. Different form of charging, USB C vs Micro USB. (All forms of charging currently outdated.)
4. No strap offering.
5. Bottom side not revealed. (Unknown if compatible with current track strap options.)
6. Significantly less IR sensors, could mean poor tracking especially if you move around or have objects in your space.
7. Compatible base stations unknown. (Could only work with V2 Stations and not V1.)
8. Kickstarter was supposed to launch in January, it's at the time or writing unknown if it will launch at all. But has been alleged to be launching sometime between now and March with full finish release by the end of the year.

Don't get me wrong, I am someone who deeply wants more VR tech to come out. Especially at cheaper costs that have better performance then what is currently out. If you think I'm fond of upgrading my PC from what already cost me 10,000 USD to make and my entire VR setup, you are deeply mistaken..

Its per avatar based on its armature. Most of the commonly used base models often have a FBT supporting armature. But custom models VERY often do not!

So your basic e-boy or e-girl "should" work with FBT as well with a fair chunk of protogens, rexes, hopkins, and/or the other mass production models.

Custom models though. They break, in multiple ways. Not retextures or chop shop jobs. Custom and unique models even if still rather humanoid. Iv seen legs that both stick to the same foot tracker (Alaster from Hasbin Hotel), models compress flat (too many to list), twist into an abomination (my first avatar that has a REALLY ♥♥♥♥♥♥ armature), go hunchbacked, tilted hips, sink into our float above the ground, as well as have the legs be too long/short and be kept permanently bent or staright.


It's a personal taste, but I hate being in a common base model and look for custom avatars. Even got into making my own avatars because I wanted something more unique. Often a unique model needs a unique armature and that's when FBT breaks.
