Create prefab from my FBX

Hi, I’m sorry but my english is not good.

I want to create prefab from my FBX, but i don’t need to all objects from FBX.
And I must take only those object that I need and then create prebaf, plees help.

If I am understanding your correctly, what you will want to do is drag whatever object you want to be a prefab from the “Heiarchy” panel to the “Project” panel. It will turn blue to show it is a prefab.
