Multiplayer Map Design - Volumes

I have been experimenting with implementation of various types of volumes, including trigger volumes and water volumes within my map, cutting away pieces of floor using the brushes and adding in surface actors to show water or other such fluids like slime or lava.

Within my concept I'm not too sure to whether or not fluid volumes will be suitable to the theme of the level and will be experimenting some more to see what I can produce which may fit the level.

I have also been experimenting with some post processing volumes which can be seen when the second water volume is entered in the video below, making use of motion blur, the options available to me within post processing volumes will likely be modified at points in the future.

I am still yet to possibly design another floor to the map, contemplating a lower, underground level to again expand the playable area, whilst keeping the map size at a format which isn't too open or vast. Some water volumes and other volumes may be implemented in either the existing levels or an underground portion, any changes to volumes will be detailed in a later post.
