Hello,

in this linked video:

Is there a strange flicker on the pavement?
I thought it was the reflection set by the material.
However, this flickering was also present when the reflection was switched off.
was still present.

Does anyone have any idea where this flickering is coming from?

Bye

Hi a.drexler
Maybe it’s not a reflection of the sidewalk, but a reflection of another material, maybe it’s the glass canopy, maybe the roughness with the light gives this effect.
I hope this is the problem for you :smiling_face: :smiling_face: :smiling_face:

Hello Riccardofertelli,

thanks for your tip.
But as it now turns out, it’s the HDRI sky!
Why ever??
Let’s see if I can find out?

If I switch to the other sky, the flickering is reduced to
on the pavement in the video is gone!

This should not be the case!
To me it looks like another error in the programme.

I will make the project available to the support team and
hope that they can tell me where the problem is and how to fix it.
and how I can best work around it.
Because I want to use the HDRI sky.

Bye
Andreas

Hi a.drexler,

Thank you for your feedback! You can try to keep the HDRI position(now you rotate it) when you output the video. Now we just suppot to calculate the stable HDRI

If you still have this problem., you can send the model to us. Feel free to tell us any questions.

Hello Bruce,
that was it!

Thanks for the tip! :slight_smile:

However, turning the HDRI sky should trigger such a
not a flicker!
