Shaking camera/Child object of Trackable in Unity,object track

Hello,

I am new in Unity and try to attach a label/3D-object to an Object Target created in Wikitude Studio (based on pictures, not on video) and imported to Unity

1. When I attach a label to the Object Target in Wikitude Studio, everything works excellent, no label shaking, the label sticks perfectly to the Object Target.

2. When I try the same in Unity, the Text/3D-object attached to the Object Target is shaking like crazy and doesn't stick to the Object Target.

Under Unity I've tried the following:

• to attach a Text Mesh as a child of Trackable --> shaking + not sticking to the object target

• to create a 3D object (e.g. a Sphere) as a child of Trackable --> then to create a separate UI text that I linked to the sphere with a simple script --> shaking + not sticking to the object target

• to attach an UI text as a child of Trackable --> shaking + not sticking to the object target

In all these attempts I attached also the C# script named "Smooth Follow" to the Wikitude Camera, but useless. The "Transform" parameters of the camera are changing like crazy during pointing the phone to the physical target, even if I fix the phone on the table (I cannot upload videos unfortunately).

I also tried different settings for the Wikitude Camera, like e.g. different field of views, different clipping panes, I played with the camera distance and rotation, but useless.

I built the project and tried again, but the same shacking and not-sticking to the object target happens.

I activated also the digital stabilizer of my Samsung Note 8 phone, useless.

Question: I suppose that the Object Target quality is quite good, as long as in Wikitude Studio the recognition happens instantly and the label sticks perfectly to the object target.

What is the solution for that?

Thank you in advance for any support or piece of advice! Catalin
