I want to have an object visible in the hierarchy, but hide its children. This is easily doable. But then, if I set the visibility (aka, the little eye icon), its children don’t disappear.
So I tried code. But it seems like it’s impossible to set the visibility via code for objects that are hidden in the hierarchy.
In other words, this code doesn’t work:
gameObject.hideFlags = HideFlags.HideInHierarchy;
SceneVisibilityManager.instance.Hide(gameObject, false);
As in, the object is hidden in the hierarchy but still visible in the scene.
Is there a way to do what I’m thinking?

Oh sorry, it was unclear to me that you were trying to do it to something with that flag, I thought you were trying to use the flag as a later attempt to hide it in the scene. Sounds like a bug that it cares about hideflags and skips the children. Interesting that you need this though, I wonder what you're making haha
– vertxxyzYeah either a bug, or an incompatibility of some sort. I might file it as an issue actually. I'm making a tool to hide the children of a Prefab. It all works fine, but at the moment it's incompatible with scene visibility options for this reason. You would hide the root, but would have no way to hide the children...
