Emission Shader.¶
The Emission node is used to add Lambertian emission shader. This can for example, be used for material and light surface outputs.
По умолчанию Cycles использует физически корректный спад света, в то время, как рендер Blender использует сглаженный спад света с расстоянием. Подобного эффекта можно достичь использованием узла «Спад света» с параметром «Гладко».
Light strength for point, spot and area lights is specified in Watts. This means you typically need higher values than Blender Internal, as you could not use a 1W light to light a room; you need something stronger like a 100W light.
Sun lights are specified in Watts/m2, which require much smaller values like 1 W/m2. This can be confusing, but specifying strength in Watts would not have been convenient; the real sun for example has strength 384.6×1024W. Emission shaders on meshes are also in Watts/m2.
Входы¶
- Цвет
Цвет излучаемого света.
- Сила
Strength of the emitted light. For point and area lights, the unit is Watts. For materials, a value of 1.0 will ensure that the object in the image has the exact same color as the Color input, i.e. make it „shadeless“.
Свойства¶
Этот узел не содержит свойств.
Выходы¶
- Узел «Излучение»
The Emission shader output can both be plugged into the Surface Input as well as the Volume Input of the Material Output node.
