You want the cull volume to encompass all of the objects that you want culled. In the above screenshot, just look at the Cull Distance Volume settings.
So there seems to be an issue with culling an object that is set to Movable. Set all of the Static Meshes that you want culled to Static and they should cull correctly after that. I am currently looking into why Movable objects can’t be culled and will update as soon as I have an answer.
To make sure that the clouds aren’t culedl (which is actually the entire sky sphere culling) you will need to go into the BP_Sky_Sphere.
- Find it in the Scene Outliner and double click it.
- Under the Components panel click the Sky Sphere mesh.
- In the Details panel under Rendering, uncheck Allow Cull Distance then compile and save.
