How do I seperate an object?

As I wrote before: I am working on a game map.


I have now joined all my mesh together and cleaned it. I need now to seperate the objects but I can’t find any function to do it. How do I split an object into several new ones?



while in edit mode select the parts you want to be a seprate object and then press p and chose to seperate selected . come out of edit mode and it will now be a seperate object.

THANKS! More I use Blender the better I like it!
