What I want is just like the title says

For ones who don't understand: I have the prefab with many children and subchildren in these children. This prefab have the renderer in subchild, I want to instantiate that subchild whenever I press "A", which is the best way?

Here is my trouble right now

1- The prefab just shows the first level children, not show the subchild, so I can't drag the subchild to the script and instantiate it :(

2- If I use the "find" command to find the child. It's will make game slower, whenever I press "A" won't It?

Anyone has another idea?

I'm getting crazy about this for 2 days thinking, searching, etc

Thanks a a lot and appreciate!
