Why i can't detect the 360 degree rotation with the avatar?

Nuitrack SDK Unity3D

I am using Orbecc Astra 2 sensor and using NuitrackAvatar Script to control the avatar. The only thing i am having a problem now is that when i rotate 360 degree, the Avatar doesn’t follow but is clamped at kind of 180 degree rotation and then resume when i face again the sensor. Is there built in restriction or what as i couldn’t find any help in the relevant scripts.

Hi @Salman

For 360 degree rotations, use Nuitrack AI. The “AI mode” allows you to make large rotations (even 360 degrees), you can try it by checking the AI on the NuitrackManager component

Thank you @irakli that did the trick. Is there a way to stabilize the character Avatar like it kind of not stable at a place like accuracy of standing where it should be is missing. When movement or hands movement the character position also moves a little either up down or left right. It is very little in magnitude but still is there a way to fix it?

This worked but also the sensor is having a hard time to detect the player. Like it forgets and detects at the same time and causing blinking kind of issue. Maybe it is because of the extra processing?
Is there a way that when player sits down then the waist should go down rather than feet goes towards the waist?

Hello @Salman

In a standard avatar, the waist moves down when squatting. Could you send us a video of the problem?

Also, to improve the quality of tracking, it is advisable to prepare the environment nuitrack-sdk/doc/General_preparations.md at master · 3DiVi/nuitrack-sdk · GitHub

Thanks for the video demo. But the issue is that Nuitrack avatar script using brings the waist down but also brings the position of the avatar down too. That is a real pain in the head for me

@Salman

Unfortunately, I don’t quite understand what the problem is yet (videos, pictures, or anything else would help a lot).
Perhaps you would like the avatar not to “hang in the air”, but to be “nailed” to the floor? Now NuitrackAvatar provides movement in the camera space and floor is not taken into account in any way. (but we plan to add this option in the future)
Or maybe such an avatar is not suitable for you in principle, then you can create your own avatar according to these instructions
