Hello, Clouds currently cannot be seen from above out of the box. They will be hidden by the fog at the moment. Weather effects and fog will work correctly. You may need to tweak the weather effects for rts games as they are designed to be used in first and third person views. But they are just unity particle effects and can be swapped for your own. Also all effects like fog lighting and so on are scene wide. If you plan to zoom out and want one area dark and rainy and another area it is clear and bright it won't work. If you plan to not zooming out that far and just hover over your terrain you could use the zone feature to have different weather on different parts of your map but you only see the weather in your current zone.
