Hi,
Interesting, I added instanced rendering to my 3Dtree (leaves mesh now
instanced) and CPU load decreased from ~55% at 5 years old tree to
~35%... Good?! But I see that when I rotating the tree with the mouse I
see low FPS...
I have Intel Pentium with HD graphics embedded to CPU.
Is it normal? I just sitting and thinking - to make commit or not... :)

Hi Igor,
Instancing is already supported by Qt3D.
QGeometryRenderer has properties for instanceCount and firstInstance.
https://doc.qt.io/qt-5/qt3drender-qgeometryrenderer.html
When instanceCount is higher than 1, Qt3D will use instanced draw calls.
Also QAttribute has a divisor property you can use to control the rate
at which vertex attributes are read (per vertex, per instance ...).
We don't have higher level elements that make use of instancing yet. We
have ideas about having something like a NodeInstantiator that does
instancing for you under the hood, hopefully for 5.11 or 5.12.

Hello,
What's the plans/state of instanced rendering in Qt 3D?
Thank you.
