Узел «Путь света»

Узел Light Path.

The Light Path node is used to find out for which kind of incoming ray the shader is being executed; particularly useful for non-physically-based tricks. More information about the meaning of each type is in the Light Paths documentation.

Выходы

Луч из камеры

1.0 if shading is executed for a camera ray, otherwise 0.0.

Луч тени

1.0 if shading is executed for a shadow ray, otherwise 0.0.

Диффузный луч

1.0 if shading is executed for a diffuse ray, otherwise 0.0.

Луч глянца

1.0 if shading is executed for a glossy ray, otherwise 0.0.

Is Singular Ray Cycles Only

1.0 if shading is executed for a singular ray, otherwise 0.0.

Is Reflection Ray Cycles Only

1.0 if shading is executed for a reflection ray, otherwise 0.0.

Is Transmission Ray Cycles Only

1.0 if shading is executed for a transmission ray, otherwise 0.0.

Ray Length Cycles Only

Расстояние, пройденное лучом света после последнего отскока или от камеры.

Глубина луча

Number of times the ray has been reflected or transmitted on interaction with a surface.

Примечание

Проход луча через прозрачный шейдер не увеличивает счётчик «отскоков».

Diffuse Depth Cycles Only

Number of times the ray has gone through diffuse reflection or transmission.

Glossy Depth Cycles Only

Number of times the ray has gone through glossy reflection or transmission.

Transparent Depth Cycles Only

Возвращает количество прозрачных поверхностей, через которые прошёл луч света.

Transmission Depth Cycles Only

Replace a Transmission light path after X bounces with another shader, e.g. a Diffuse one. This can be used to avoid black surfaces, due to low amount of max bounces.
