Sky Atmosphere doesn't work if Forward Shading is enabled

Hi!

This is the first time I develop a VR game with Unreal 5.3.2.

I have followed some performance recommendations from Unreal and I have enabled Forward Shading:

I want to get something like this:

To do it I have added a directional light and a sky atmosphere to the level. The above image is from the FPS template.

If I enable the Forward shading, then I don’t see the sky atmosphere.

How can I get that effect with Forward Shading is enabled?

Thanks.
