Visibility issue

[Momowarlord]

When I put doodad structures on a cliff they are just black like shadow. How I can make them visible?

 

[Pyrogasm]

If they're doodads and don't need collision (destructibles have collision, doodads don't) you could instead make them locusted neutral-passive units and see if that changes how they are displayed due to fog of war.

The easiest solution would be to make a region that covers those doodads and create a visibility modifier over it that gives vision to players. Enable/disable the visibility as units move close/far away.
