I’ve searched the docs, google and these forums. What is the orange dot on some of the icons in W.O. mean?
Displays the Mobility setting for that Actor: orange for Movable, yellow for Stationary, and nothing for Static.
I bought this model pack. Should decals (all) and spot lights (all) have that orange dot?
Depends on what you’re doing. It’s easy enough to change from their properties - if you’re wanting the spot lights or decals to move, they should be set as movable. If they’re set as static, and you’re using static lighting - that allows the engine to calculate the lighting and shadows as it knows they will not move.
