2. type /aidebug 6, then /dropwaypoints 1
3. Optionnaly, you can change max waypoint seeing distance with /showwaypointsradius (value, default 200).
4. Run in all the map, go on playerstarts and team playerstarts, ammo, bases, flags (avoid floating flags !!), avoid jumping while unnecessary. [do not weapon jump and take too risks]

Tip : You have 2 maps with same geometry but not same textures or entities ? type /savewaypoints (mapname)
6. Type /aidebug 0 and /dropwaypoints 0
7.
1. Go in edit mode and type /skytexture 0
