Subject: Re: [Interest] [Qt3d] Textures flickering

Hi Oleg,
* Change the near plane and far plane properties of the camera so you
get greater depth precision by reducing the range covered
* Use a higher bit depth depth buffer via QSurfaceFormat
* Render your scene in multiple passes using different camera z-range
for each part and clearing the depth buffer in between.
Cheers,
Sean

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…
