It gets every chil I have a prefab in scene and I want to access a child of that prefab, Structure of that prefab is like this: transform.FindChild return just first level child and loop in that transform is loop in first level child too: I think it's need to be a recursive method or something. I think this is a simple way to solve this ChangeChildLayer(Transform Obj) Not the answer you're looking for? For that case there is also GetComponentsInChildren (plural) which gets you an array of all the components in the children of that object. t:meshCollider and t:boxCollider also work to further refine your search if needed. This works for 1 level of children but if there are nested children you need to accomplish this via recursion. -Layout Translation However, both the object folder and separator methods can make the scene hierarchy in Unity easier to work with.

I'd add that relying on objects names or hierarchy order may not always be the safest solution. how do i get all and loop through to get specific name object.
