Light

In every Light you'll find theses same parameters (except Ambient Light Light coming from every directions Read More ): - one color by light passes : diffuse / specular / volumetric : see components of Surface Display geometry's triangles as a surface Read More and Volumetric Light Cast rays to generate light where there is no shadows Read More to understand the matching parameters of theses emissions. - Attenuation is a curve representing the intensity of the light given the distance from it's emission point. Attenuation is in falloff by default but can by set to any Function Function that maps a number (percentage, time, etc.) to a value Read More . Note that the falloff is represented inside the Viewport Preview and edit your content Read More through the lights helpers.


Note that in the case of Directional Light Orthographic light casting shadows Read More and Projector Light Light emitted from a point in a direction using any 2D Layer as a map. Cast shadows Read More (and more to come) if you go in advanced parameters mode, you'll have access to the Shadow parameters and scene bounding box which is the box in which shadows will be computed. In that section you can adjust the shadow map samples and narrow the area where shadow will be computed.


Last thing you must now about lights is that by default the got a whit map as input (which is easier to adjust their color and all) but in any light (again except Ambient Light Light coming from every directions Read More ) you can put anything as light map. Here I took an example from the Smode pack and put it under my projector Light.
