In either case, please create a bug report with, if possible, a small example

I can have a dummy z value as 1 for the calculation. The problem is

You can’t convert 2d coordinates to a 3d position because you are missing the z
coordinate. It is similar problem like with picking objects in a 3D scene - you
can unproject a 2d screen coordinate to a vector/ray in your 3d scene and then

Check it in Qt 5.14, recursive property helps, but why? I'm confused,

Lack of recursive QLayer is the first think I thought of. That's why there

From what I can see in the code, QText2DEntity doesn't draw anything,

Therefore if you set the QLayer on QText2DEntity, it won't be set on the
internal entities and won't draw.

The contours/silhouetting proved a bit of a leap right now so I backed off
to look at the offscreen side of it.
I removed the depth pass and am just trying to get a simple frame graph
working for on-and-off screen capture.
I have the following frame graph (in YAML, but it should be clear):

Yes. Set the primitiveType property to LineStrip and you can specify

Thank you very much for the detailed responses!
This has given me a lot more to work on/understand.
The ClearBuffers part was very useful for understanding what's actually
happening. This would be good info to drop into the QClearBuffers docs.
I guess I now have to dive into render

Thank you so much Paul!
That gives me something to start working on/pick apart. I see now how
onscreen vs. offscreen works and can concentrate on getting the onscreen
working the way I want first since they are very similar.

My bad. Windows Deployment nothing to do with my issue. In fact this was in
release mode even in qt creator due to my mistake with #ifdef QT_DEBUG and
not adding entities to QLayerFilter %)
Sorry for bothering.

Build app without models and its size reduced by size of models. So they
are the part of exe as other resources, right? But not displayed :(

I filed a bug report:
https://bugreports.qt.io/browse/QTBUG-69802
I couldn't figure out how to turn it off through the public API, but I did
come up with a fragile hack to turn it off.
In your inherited camera controller (or, subclass one of the existing ones):

Mike, thanks.
Yes you are right. This is z-conflict.
This model is rendered fine, without flickering in another project with
disabled fragment depth writes to depth buffer.
How can I increase precision of z-buffer in qt 3d?

Hi
hard to say from the short video, but it looks like you may have z fighting
going on, two coinciding meshes and the lack on precision causing this
flickering…
