Start param means the distance (in meters) after which the attenuation starts to take effect (dist = distance – start). Unless you are familiar with whatever these calcs are based (and I am not) I’d say just see what happens when playing with the numbers.\\   * **//Attenuation//**:\\ Light intensity drop-off over distance.

In meters.\\  Value can be unlimited, this parameter determines the range that the light source takes effect. Terrain environmental color will be bathed by ambient light color within the range and its covered objects will reflect the light color.

Any minus value passed will be treated as 0 (100% brightness).

In other words, this parameter will turn the source into spotlight and sharpens its light circle border.

In further explanation, a less bright source can’t be seen out of the range on the land but still visible on the sea, and a bright enough source won’t be effected by the passed range which is still visible out of the range.

 Since game version 2.06 it's possible to define directional lights. Since game version 2.06 it's possible to define directional lights.
-In the Basic Params leaf you can select whether the light emitter type is point or directional. Selecting directional allows to to use this Directional Leaf to set the "light cone" parameters.+In the [[led_ui#light_params|Light Params]] leaf you can select whether the light emitter type is point or directional.

-  * **//Outer Angle//**:\\ Basically there are two "layers" of the light cone on top of each other, outer and inner. This defines the outer angle which is softer. If outer angle is smaller than inner angle the light cone has sharp edges and if the outer angle is larger than inner angle the edges are soft.\\ It is currebtly unknown how these affect the volumetric shape when such is used.+You can rotate the light in 3D using the Eden //Rotation Widget// or in 2D by holding down ``SHIFT`` and dragging the direction arrow from the emitter (press and hold left mouse over the emitter and move the mouse, like with any Eden entity).

-  * **//Volumetric shape//**:\\ Path to a model used for the "3D light cone" you can see for example on vehicle lights and such. There literally no info at all about this other than apparently the shapes that come with the game itself don't work with this because they're pointing in the wrong direction, or something like that.+  ** **//Volumetric shape//**:\\ Path to a model used for the "3D light cone" you can see for example on vehicle lights and such. The game comes with these shapes but for some reason they do not function correctly with this as they're basically inverted so the origin of the cone is away from the emitter towards where the emitted light is pointing, and the shape is pointing at the emitter. There is no information on how to make custom shapes yet.
