Поверхность (surface)

Прямые лучи (direct light)

Эта опция ограничивает максимальную интенсивность света, которую может отражать поверхность. Это уменьшает шум cтупенчатости и количество «светлячков» за счёт точности. Установка этой опции на 0.0 полностью отключает отсечение. Более низкие значения оказывают большее влияние на результирующее изображение, чем более высокие значения.

Отражённые лучи (indirect light)

Similar to Direct Light but limits the maximum light intensity reflected using ray-tracing and light-probes. This also limits the intensity of the world lighting since it is considered indirect light.

Примечание

These options provide a way to limit Fireflies and Aliasing of highly reflective surfaces and dense volumes. However, as values are clamped, intentionally bright highlights may also be reduced.

Care must be taken to balance firefly reduction against loss of desired brightness.

Объём* (volume)

Прямые лучи (direct light)

The same as Surface Direct Light but applied to volume direct lighting.

Отражённые лучи (indirect light)

The same as Surface Indirect Light but applied to volume indirect lighting.

The intensity controls scale the evaluated lighting contribution in EEVEE. They do not modify ray depth, sampling, accumulation, or performance characteristics.

Прямые лучи (direct light)

Scales the contribution of direct lighting, including light sources that directly illuminate surfaces and volumes.

Increasing this value strengthens highlights and direct illumination. Lowering it reduces the apparent strength of light sources without modifying their energy settings.

Отражённые лучи (indirect light)

Scales the contribution of indirect lighting, including bounced light from ray tracing and light probes.

This affects global illumination and world lighting. It can be used to strengthen or weaken the perceived bounce light in a scene.

The scaling is applied after clamping, preserving firefly suppression behavior. This makes the result behave similarly to a post-lighting compositing adjustment, while remaining consistent across dithered and blended materials.

These controls are useful for adjusting lighting balance in large environments, fine-tuning indirect illumination, and balancing direct versus indirect contribution without modifying individual light settings
