Then I would stay with the first solution I proposed, it will be more
flexible in your case: regular text2dentity with custom frame graph
branch and custom camera.
There is just one thing to be aware about the text2dentity, the entity
doesn't do the rendering itself: it contains another entity
The number of Text2D elements is not known in advance and may differ.
It's a simulation environment, where some textual information is added
to a fairly high number of elements.
To avoid the data management for different kinds of entities my first
idea was to create a specialized Text2d entity
You're welcome.
I will most probably have to implement the same feature in a near future
for the project I'm currently working on.
If making the custom camera is too much complex, there is a more basic
way but involving more data management (depending on how much 2d text
entities you have to
Hi David,
thanks for the answer. I wasn't thinking of that, as my knowledge about
framegraphs is very limited. But this helps me further.

If you rendering in QtQuick you can use a Text{} item and project it's
position into screen space.

Hi Oleg,
thank you so much for your comment. I saw your entry in the bug tracker
and therefore I tried to go the way with the custom material.
Unfortunately I cannot access the underlying material definition of the
utility classes that are used to render the text in Text2DEntity. As
they are
Hello Volker,
I guess you can achieve it with regular QText2DEntity, with a specific
frame graph branch in your rendering for your 2d text, a layer filter
and a custom camera (based on your main camera).

Hi Volker,
Yes, you have to add custom material because Qt3DRender::QShaderProgram s
of default materials are inside private class, so you can't change shaders'
code source.
Take a look at https://codereview.qt-project.org/#/c/182053/ (that was for

Hi all,
when building a rather complex Qt3D-Scene I needed some 2D-Text that has
a 3D position, is always facing the camera, and fixed in size,
independent of the camera settings.
While looking over the components provided by Qt3D I stumbled across
Text2DEntity and thought about how it can b
