What is FBT anyway?
テトラちゃんWhat is FBT in the first place If you know nothing at all about FBT equipment, please check the link below first.
This article alone will give you a general description of FBTs, including the tools they use, etc.

How do I set up FBT?
テトラちゃん
1. setting up the ‘device itself’ (hardware settings, charging, mounting on the body, belt settings, etc.)
2. ‘Software for the device and HMD’ settings
3. ‘Settings on the VRchat side’ (when full tiger, a menu for adjusting the FBT will appear)
4. ‘Adjustments to be made each time on the VRchat side (hereafter referred to as calibration)’.
If you see someone doing a T-pose in front of a mirror on VRchat, you can assume that they are in the middle of calibration 4 (see video).
About calibration, which is essential every time you synchronise your body with your VRchat avatar.
テトラちゃんVRchatアバターと体を同期させるやり方
- [How to do it] (This operation is generally called calibration.)
(1) Before entering, turn on the VIVE Tracker 3.0 on Mr White Tights’ side and confirm that it is green.
(ii) Click FBT in the menu and T-pose. Check that the parts worn by White Tights and the avatar’s body match.
Check if the avatar’s body matches the part of the body wearing the white tights.
(3) If three white balls (as many as the number of trackers you put on) are aligned with the avatar at the time of T Pose
Pull the index finger trigger.
By the way, even if the type of full tracker is different for Quest and VIVE, this calibration method is the same as the VRchat side adjustment.
The method of calibration is almost the same, because it is adjusted on the VRchat side.
The following are the specific calibration settings for becoming FBT.
Now, please refer to the respective dedicated pages for the settings of the device itself, etc.
How to set up FBT, first half (device section).
テトラちゃん
1. setting up the ‘device itself’ (hardware settings, charging, mounting on the body, belt settings, etc.)
2. setting up the ‘software for the device and HMD’.
The first step is to set up the ‘software for the device and HMD’! Please see each page for a description of how we actually did it!
HMD setup
The main prerequisite is that the HMD is ready to be used on its own. For lighthouse HTC products (SteamVR), please complete the HMD set-up, including room set-up, and for the Quest series, please complete the Guardian settings. In particular, it is often the case that the Guardian settings for Quest have improved after re-setting them.
If this is not done properly, the HMD may be buried in the floor, or the white ball may not come out of the floor, etc.
Unimotion, HaritraX Wireless and mocopi.
HaritraX Wireless, Unimotion and Mokopi are all available here when I am setting up my own.

We get a lot of enquiries about Haritra and Unimotion, so make sure you check the official and discord before enquiring.
We sometimes receive enquiries on our website, but there are very many people who are not on the discord.
Please make sure you install the discord, as there are many places that support it as well as online searches.
When the Vive tracker + HMD is Quest series
If your HMD is Quest + VD or similar, please check the following after understanding that it is not officially supported in the first place.

If you wear the Vive tracker on your chest separately
In the case of the Vive tracker, many people may not know how to wear the tracker on their chest, so we explain how to put it on.
There are two ways: you can use the chest tracking belt from Eoz, or you can make your own bra-like device with a waist tracking belt and garter belt. Currently, there are various fixed devices for Gopro and so on.
I use this method because it cannot be connected to the elbow tracker. When fixed in this way, elbow trackers can also be connected and fixed with the garter belt, so each tracker does not shift and the belt does not need to be readjusted. This creates a more immersive experience, but the degree of external metamorphosis is overwhelmingly greater. (Lastly important)
【胸トラッカーベルトの身に着け方】

Attach the garter belt to the waist strap like the shoulder strap of a bra.
(iii) As if wearing a bra, if the tracker and strap worn on the chest are not screw-fastened properly, the tracker will easily rotate. If it rotates, the avatar will be squishy as shown in the video. As a result, the estimation of other joints will also be lax.

3. ‘Settings on the VRchat side’ (when you become a full tiger, you will get a menu for FBT adjustment)
4. ‘Adjustments to be made each time on the VRchat side (hereafter referred to as calibration)’
If you see someone doing a T-pose on VRchat, for example in front of a mirror, you can assume that they are in the middle of the 4. calibration (see video). If you see someone in a T-pose in front of a mirror on VRchat, assume that they are in the middle of the calibration in 4!
This section starts from 4.1. In other words, this section is for people who have all the equipment and have already set up their VRchat account, etc.

もう一度全体的な流れを説明すると
テトラちゃん
In VRChat’s World, stand in front of the full-length mirror.
Press Y on the controller to open the quick menu.
In the Launch Pad tab, select Calibrate FBT.
The avatar assumes a T-pose and there is a white ball attached to the avatar’s body. This white ball is the tracker attached to the body.
∙ Move the body and align the tracker with the corresponding body part of the avatar. Make sure the white ball overlaps the avatar’s ankle.
▪ Align your hands with the avatar’s hands and pull the left and right controller triggers simultaneously.
キャリブレーションの設定をログイン時から解説
全体的な手順
1. launch VRChat & select an avatar.
1. launch VRChat from SteamVR and login.
2. select an avatar to use. At this point, select an avatar that supports full body tracking.
2. Set the User Real Height to the value of the real height *Some IMU-based full-traffic devices are described to change this value.
1. Go to Menu > Settings and display the User Real Height item.
2. Adjust the height so that the white balls of both feet overlap around the ‘ankles’. (In the default home world, the ball is placed in the centre of the world.)
3. In the Menu > Settings > Tracking and IK, select Hip Lock.
(3) Calibration (the appropriate User Real Height differs depending on the avatar).
1. select Calibrate FBT to display the white ball. If this option is not selected, there is a big possibility that the device is not recognised in the first place and data is not sent from each device to VRchat, so recheck the settings there.
*Basically, if the device is recognised by SteamVR, there is a display for devices other than the HMD + controller. If this is not the case, it is not recognised. The picture shows the display for the Vive Ultimate Tracker, with the green icon being the Vive Ultimate Tracker (the icons are different for each device). If it is a Haritra system, it will be a tiger symbol. For more information, check the official version of each device).
2. face firmly forward, avoid inward or outward straddling, and open the legs moderately.
3. check that the white ball overlaps the avatar’s ankle area.
4. simultaneously pull the left and right controller triggers. Completion.
Explanation of the locking position of the FBT (FBT:Lock~).
公式ドキュメントより：https://docs.vrchat.com/docs/ik-20-features-and-options 引用
You can choose the reference to be fixed using FBT:Lock in the menu field > Settings > Tracking and IK. The adjustment here is also important. Menu > Settings > IK: 2.0 setting, so make sure that IK: Legacy is not selected.
Hip Lock: Default. Use the position of the hips as the standard. Easier to clean the standing posture. This is recommended for the first full tiger.
Head Lock: Based on the head position. Suitable for when avatars are in close proximity to each other and looking at each other, or when lying down and being stroked. Head Lock: This is a good option for when avatars are close to each other and looking at each other, or when they are lying down and being touched.
All Lock: The position of the head is based on the number of other tracking points. The more tracking points, the more difficult it is. Most difficult because the body structure needs to be close to that of the avatar. Deprecated at the beginning due to the difficult choice, as it often does not match anywhere.
Avatar Measurement explained.
・Avatar Measurement：腕が伸び切らない場合は、腕にする。
Avatar Measurement: if the arms are not fully extended, make them arms.
User Real Height is in principle real height. Officials have announced that it should always be Real Height. Some full tiger device manufacturers (vivetracker and Ultimate tracker are real height, often IMU method, camera full tiger, etc.) state that it should be changed, so please check the official device manufacturer’s website, The change is stated to be made. (Please note that the height in the article is set to 171 cm, but the image was taken from the official website with the height set appropriately for the article, so my height is not 171 cm).
The default setting of the advanced specifications below says it all, but if you are further away than the default value of 60 cm, it will not be recognised as a tracker. Conversely, if the foot tracking point is a little below the floor and within the default value of 60 cm, the avatar’s feet will not rise.
Other options explained (for advanced users, no need to tinker with the principle at all).
The above problem solves most of the above issues, but adds a supplemental one.
–custom-arm-ratio=‘0.4537’ Adjusts the ratio at which the avatar is scaled. The default is ‘0.4537’ and smaller values around ‘0.415’ may give an improved fit. if the arms do not fully extend when set to arms in Avatar Measurement, tweaking the default values here may help. smaller values The default value of ‘around 0.415’ may give an improved fit, so inviting 0.415 and lower may improve the fit.
–disable-shoulder-tracking -: adjustment of elbow trackers used for some types of IMU systems Some types of IMU-only based arm trackers can avoid problems with this method. [Note: but beginners do not need to tamper with it, see the official IMU manual]
–enable-ik-debug-logging : add additional IK-related output to the log, to be used when reporting IK bugs or problems.
–calibration-range=‘0.6’ – : Determines the distance (in metres) from the predicted support junction point to search for when calibrating. The default value is defined in the area of a sphere of 0.6 metres (60 cm). Applicable to foot, thigh, hip, upper arm and chest trackers.
–freeze-tracking-on-disconnect – Enabling this will freeze the tracker in place against the player when it is disconnected. To remove frozen trackers, re-calibrate. If all trackers are disconnected and the calibration option is no longer displayed, cycling through the avatar measurement options will also unfreeze the trackers.

より和訳
ミントWith IK 2.0 as of July 2022, if the avatar and the white sphere are too far off, they may not synchronise!
Please note that in this case, the problem is almost always in the equipment settings and this calibration will not cure the problem!

トラブルが発生した場合
【トラブル１】身体がぐにゃぐにゃになっている、ねじれている
Viveトラッカーの場合、体と密着していない状態でキャリブレーションしていないケースがほとんどです。
また、基本的にVRchat上でのキャリブレーションした後に各デバイスやトラッカーを動かしたりすると、追従してぐにゃぐにゃになります。VRchat上でのキャリブレーションを再びしましょう。
特に多いのが、QuestやPicoシリーズでVivetrackerでしたら、「②無線フルトラ（OpenVR-Space Calibratorの導入）の設定をする。」のキャリブレーションをやっていないか、キャリブレーションがうまくいっていません。
トラッカーベルトとねじを固定したあと、キャリブレーションをやり直してください。
【トラブル２】viveトラッカーの白い玉がキャリブレーション時にのみ、変な位置に移動して、対応できない場合
トラッカーが変な位置に移動して、対応できない場合
- What to do if the tracker does not go near the avatar If steps 1), 2) and 3) do not work, do 4) and readjust.
You can do this with a new adjustment on the VRchat side.
(1) Sometimes the white ball flies away and you can’t get it to work with the T-shape.
In this case, the right elbow has moved away from the avatar
(ii) Change the direction and position of your body so that it doesn’t fly away!
(iii) However, even if you are in a slightly odd position, the IK update has made the action better.
You could pull the trigger at the right place and readjust it again with the mirror.
[Trouble 3] Body is squishy, body position is twisted, body does not fit, white ball of foot is buried in the floor,
Re-check room set-up and Guardian settings [particularly problems with white ball buried in the floor].
Complete the HMD set-up, including room set-up for HTC products with the Lighthouse method (SteamVR) and Guardian settings for the Quest series. In particular, it is often the case that the problem of the white ball on the feet filling up is improved by re-setting the Guardian settings in Quest.
The originally unnecessary OpenVR-Space Calibrator add-on is turned on [if it is not required by the IMU system].
For those who also use Vivetracker fulltra equipment with Quest or Pico series, ‘(2) Configure the wireless fulltra (OpenVR-Space Calibrator installation)’. The problem is that the OpenVR-Space Calibrator is still switched on in the ‘1)’ section: the IMU system, especially HaritoraX wireless, is officially written to be switched off. As a rule, it works better if it is switched off.
OpenVR-Space Calibrator calibration is not carried out [when using Vivetracker with Quest or Pico series].
If not carried out, it is messed up in the initial stages. For more information, see.
QuestProで、11点無線HMDフルトラ＋Indexコン＋フェイシャル＋アイトラッキングの完全体フルトラになるまでの流れを紹介！【完全体フルトラ（無線フルトラ＋アイトラ＋顔トラ）】【前編】
HMD not recognised by the software of the device manufacturers’ companies [IMU system].
Another common problem is that the HMD is not recognised by the software of the device manufacturers (e.g. Unistudio) because they forgot to start the HMD and started the software of the device manufacturers first. It is important to start the HMD first and let the software of the respective company recognise it. Rebooting is effective.
Other cases where white balls are buried in the floor [IMU system].
For mocopi, HaritraX Wireless and Unimotion, see this article. Most of the problems are due to configuration issues on the device prior to calibration. The problem with the white ball of the foot being buried in the floor is more of an initial problem with the settings on the fulltra equipment side, in the case of Quest and others, it is often possible that the position is not being acquired properly and can be cured by restarting the software on the steamVR or the respective fulltra device. Check both links below for more information.
mocopi、ハリトラワイヤレス、ユニモーション、VIVEトラッカー、VRchatではどのフルトラデバイスがいいのか？全て自腹で買って実際にやってみた【2024年1月7日版】
[Trouble 4] Head is held down, slow waist movement, bent knees.
See the description in the explanation of the FBT locking position (FBT:Lock~) above, where you can choose between Head-centred and waist-centred tracking in the settings on the VRchat side. This almost always cures the problem. If the white ball is too far away from your body to begin with, refer to Trouble 3.
[Trouble 5] The pose looks as if it is being crushed by the floor.
This occurs with devices that set the floor, such as Haritra Wireless. Remove the check box that recognises the floor on the Haritra side.
If the white ball is far away from the body to begin with, or if it is an IMU system, see the same article as Trouble 3.

[Trouble 6] In the case of a Quest or similar with OpenVR-Space Calibrator with ViveTracker, if it is away from the body in the first place, is somehow out of alignment or twisted.
In the case of a Quest series + ViveTracker or similar, it is highly likely that the calibration with the OpenVR-Space Calibrator is not done properly. It depends on whether you have a tracker on your head or not, but a basic re-calibration should hopefully do the trick. Please check the calibration in the section about the OpenVR-Space Calibrator in the article below.
If this is a pain every time, we recommend considering a head tracker!
