Every level designer has their own unique way of mapping. From my previous maps I've done the layout and then added architecture
and details towards the end. I ran into problems doing it this way because brushes would not fit properly because I used incorrect sizes and mistakes but spent so much time on it I worked around the errors.
Moving on I have a new perspective on mapping and prefer to work on 1 room at a time then see where my mind takes me
I'm still fairly new to mapping and have some experience now I can only get better moving forwards.
All of my previous maps have been for bunny track so working on a CTF map will be slightly different and fun.
