i am making a map with someone and i need to give him some screen shots but i don't know how so some help would be nice
You could try this.
Open console and type devmap *your map name* (example devmap ctf_bespin)
then bind screenshot to key if already havent. (example bind F12 "screenshot" in console)
And choose Spectate from menu to move everywhere you like to go. This gives you opportunity to take aerial screenshots too since not linked to any model
