Re: [Interest] [Qt3d] Textures flickering

2018-07-29 Thread Oleg Evseev
 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
