Defo seems to be some wrinkles to iron out. Tried the waypoints out straight away. The Zombie walked at a set rate, not slowing down to match it's steps as shown in the past. I did have one of the built in CC characters walking around the same waypoints though, just in case that could be the cause of the sliding zombie walk. I also tried the Cellar demo and there was a plethora of missing objects, including the roof.
Can't say I'm keen on having to click fps game to get the option of dropping waypoints either, seems super clunky to me and should be among the normal icons that are already there. NPC waypoints are hardly an FPS only feature and would seem a more general option for all game types.
It also seems weird with particles. Select them and you have to place the icon down before you can choose the type of particle it is. Seems totally bizarre to me and not new to this build, but thought I'd mention it.
