Lighting Channels ia a rendering feature that enables you to choose what renderable surfaces are lit by specific lights.
Multiple directional lights are supported in different channels. Each primitive can be affected by only one directional light. The first lighting channel set on a primitive determines which directional light will affect it. CSM shadows from stationary or movable directional lights cast only on primitive...
Directional Lights TheDirectional Lightsimulates light that is being emitted from a source that is infinitely far away. This means that all shadows cast by this light will be parallel, making this the ideal choice for simulating sunlight. The Directional Light when placed can be set to one of ...
var lightConfig = scene.config.lights; lightConfig.enable = true; 1. 2. 3. lightConfig就是对整个场景光源设置的变量。首先设置其enbale属性为true,表示使用光源。上面分析的几种光源均可以添加或者不添加在特定场景中,并可以任意设置其光源位置及颜色分量等。 2.2 线光源 设置lightConfig属性的directional的dir...
Directional Light Mapping enables the static shadowing and diffuse normal-mapped lighting of an unlimited number of lights to be precomputed and stored into a single set of texture maps, enabling very large light counts in high-performance scenes. ...
虚幻引擎中定向光源的基础说明。 定向光源 将模拟从无限远的源头处发出的光线。这意味着此光源投射出的阴影均为平行,因此适用于模拟太阳光。定向光源放置后,可对其 移动性 进行如下设置: 静态——(左图)即无法在游戏中改变光源。这是速度最快的渲染方法,可用于已烘焙的光照。 静止——(同见左图)即光源通过 Ligh...
Although it has some limitations, particularly with Directional and Rect lights, it makes it feasible to use chromatic light functions in production. And while it has had less attention than the MegaLights system, the Light Function Atlas can be used with it, making it possible to use light ...

Full screen directional lights, we can just render a fullscreen octagon without using FastGS. In the pixel shader however, we need to recalculate the ScreenVector variable per pixel since we need to remap it to the LMS coordinate space. ...
executing commands based on the data received. This could mean turning a light on or off or rotating the device 90 degrees. There are many sorts of DMX fixtures from standard stage lights that simply turn on and off to intelligent lights that have multi-directional rotation and lighting ...
