Next to lighting from the background and any object with an emission shader, lights are another way to add light into the scene. The difference is that they are not directly visible in the rendered image, and can be more easily managed as objects of their own type.

Блік – Specular

Specular Light intensity multiplier. Use it for artistic control. Defines the intensity with which the light object will be visible in reflections on the surface of specular objects, like metals or mirrors. Setting this to 0 will make the light object disappear from specular reflections. Keep it exactly at 1.0 for photo-realistic results.

Кастомна Відстань – Custom Distance

If enabled, uses Distance as the custom attenuation distance instead of global Light Threshold. In order to avoid long setup times, this distance is first computed automatically based on a light threshold. The distance is computed at the light origin and using the inverse square falloff.

Distance – Відстань

Визначає, де вплив освітлення буде задано як 0.

Shadows – Тіні

Загальні Параметри – Common Parameters

Старт Відсіку – Clip Start

Distance from the light object at which the shadow map starts. Any object which is closer to the light than Clip Start will not cast shadows. Clip Start is only available for point, spot and area lights.

Відхил – Bias

Bias applied to the depth test to reduce self-shadowing artifacts. This determines, what size of surface details (for example, bumps) will cast shadows on the object itself. If this value is low, small bumps will cast shadows on the object’s surface. This might cause jagged shadow edge between the sunny and shadowy side of the object, but it can be smoothed out by turning on Soft Shadows

Тіні Контакту – Contact Shadows

This type of shadow exists to fix light leaking caused by bias or shadow map undersampling. It uses the depth buffer to find occluders (just like Screen Space Reflections). However, just like Screen Space Reflections it has the same limitations, namely, unknown object thickness and effect disappearing at screen edges.


The distance of action of Contact Shadows should remain quite small. They are not accurate enough to shadow the entire scene.

Distance – Відстань

Відстань простору світу, на якій шукати загороджувач простору екрана.

Відхил – Bias

Ухил, що застосовується до простеження променя, для скорочення артефактів само-затінювання.

Thickness – Товщина

Товщина пікселя, що використовується для виявлення загородження, за допомогою обробляння будь-якого потенційного загороджувача з цією товщиною.

Розкладка Каскадної Тіні – Cascaded Shadow Map

Sun lights usually illuminate a large scene with many objects, some close, some far away. To optimize shadow calculation in this situation, a technique called Cascaded Shadow Maps is used. The distance between the camera’s near clip and far clip point is divided into as many equal intervals (called cascades) as you set the Count parameter below. For each cascade a different resolution shadow will be displayed: higher resolution for closer cascades and lower resolution for distant ones. Do note that cascade shadow maps are always updated because they depend on the camera position or your view origin in the 3D-Viewport. This means they have a high performance impact.


В ортогональному огляді каскади охоплюють весь діапазон глибини камери з рівномірно розподіленою точністю тіні.

Count – Рахунок

Number of cascades to use. More cascades means better shadow precision but a lower update rate.

Fade – Зникання

When the Fade is greater than 0, the size of each cascade (distance interval) is increased so that neighboring cascades overlap. Then a fade is applied in the overlapping region to provide a smooth transition between cascades. Higher values mean the cascade’s size is increased more, which decreases the available shadow resolution inside the cascade since some of it is used in the overlapping region.

Макс Відстані – Max Distance

Distance away from the view origin (or camera origin if in camera view) to cover by the cascades. If the view far clip distance is lower than Max Distance, the view far clip distance will be used. Only works in perspective view.

Розподіл – Distribution

Puts more resolution towards the near clip plane. Only works in perspective view.
