C++ Qt3D 2.0: billboard transformation and rendering widget as texture

Hi,

I am trying to get into Qt3D 2.0.
Due to this bugreport billboard tansformation was depricated and replaced with

Code:

---

QLookAtTransform

---

.
I have created plane and trying to make it always face the camera entity. But both

Code:

---

QLookAtTransform::setViewCenter()

---

and

Code:

---

QLookAtTransform::setViewVector()

---

give no result (I pass camera position and have connected camera move signal to this methods). Plane jast disapear from scene. What transformation and how must I use to make plane always face the camera?

Second question is about possibility to render custom widget (in my case qcustomplot ) inside Qt3D on plane or as a sprite. Is it possible to make with new Qt3D?

Thanks!
