Description

Expected behavior: The sky has a flickering in it.
Actual behavior: The sky should not be flickering.

Steps to reproduce

Download the null island world from: https://app.gazebosim.org/OpenRobotics/fuel/worlds/Null%20Island
Start with gz sim -r path/to/null/island.sdf

Output

@iche033 is this due to the non-NVIDIA GPU?

Dec 12 '23 20:12 azeey

I do remember seeing flickering sky issue on user laptops before. It could be a gpu / driver issue.

Dec 12 '23 22:12 iche033

Ok thanks. I will see if this error happens when i run it using a GPU and report back.

Hi! I am coming here from a post I made on Gazebo Community.

This looks like the same problem I am facing. I wrote an SDF world with a sky and a directional light, and when I toggle the shadows the sky start flickering.

Here some information about my machine, as in the first post in this issue:

Yes. So I was able to confirm that if I use a GPU then the flickering does not appear. See Image below.

I wrote an SDF world with a sky and a directional light, and when I toggle the shadows the sky start flickering.

oh sounds like the shadows (or the light) is causing the sky to flicker? One workaround would be to disable shadows for the directional light.

Jan 03 '24 18:01 iche033

Yes this worked! If I disable the shadows for my sun and enable them for the scene only, I can run the sky.

Jan 06 '24 10:01 frede791

@iche033 Is having both sets of shadows enabled still a bug?

Jan 16 '24 08:01 frede791

Is having both sets of shadows enabled still a bug?

I haven't seen any movement on this so I assume it's still an issue.

Jan 16 '24 22:01 iche033

Hi all,

I am running into the same issue.

With shadows: with_shadows

Without shadows, it is much better. However, still some flickering occurs: without_shadows

I am also running it on a laptop without GPU:

I see this issue running on multiple computers with an Nvidia GPU. Disabling cast shadows from the sun also fixes the issue for me.
