making trenches is easy to anyone with worldbuilder experience, set both of the factor things to set value, make your hight like 8.5 around like i do then make the outline of trenches well idk what to say but that will make
the actual trench then go to spline and selct objects/go into rbd/art_ambient/objects/walls/support/trenchwall_01 and uncheck one of the two things...i forget whats called cuz im not in worldbuilder now and checkmark objects at top and go along the edges of the ground whereur trenches are and then click enter and pull it up by pressing 'h' key and position it with 'space bar' and u got one side done then do same with other then uncheck objects go back into textures in the splines and find a good floorboard design then follow the trnch maybe put a texture under it so it stands out from the rest of map and such and uve got a basic trench
