Omni Light doesnt work

[Doctor-Pepper]

When i am placing Omni Light doodad on the map, i dont see any changes on the terrain.
I am using Mar Sara Night, as a lighting theme
Is there a function that i have to enable?

You need to be running the game on ultra or better to really see all lighting at work.
Also make sure the main light source is not drowning out the omni light.
Also maybe the omni light is missing its models, there are many doodads which blizzard has included the data for but no models cause this is the beta.
