Rain area (Water Overlay)

A Rain area is a feature which can override the Weather's rain with a different array of values. This allows users to simulate rain clouds moving over the project area.

Icon	Key	Unit	Range	Description	Default value
	RAIN_M	end-time, m		An array of values, each pair indicating until what time that period of rain will last and how much rain will fall in that period.	n/a

Dynamic rainfall defined by 101 different rain areas, which is shown in the mini-map halfway the animation. Animation is showing the last rain result

Notes

• A maximum of 10.000 values (5.000 pairs) can be defined per rain area.
• Up to 32.000 rain areas per Water Overlay are supported.
• It's not required to fill the entire project area with Rain areas to use the Rain area functionality. For locations without a Rain area, the Weather's rain m is applied.
• See the RAIN_M attribute for more information on the restriction on its values.
