directional light

A combination of a strong directional light and a weaker ambient light gives a natural-looking appearance to your scene.

It is possible to add a directional light component by faking the Sun either via a single spot or with an Area Light.

As said before, a directional light can be thought of as the sun, and the sun doesn't have a falloff radius or anything else.

The directional light needs to look at the object you wish to light, and needs to be double-sided.

Brightest directional light is always per-pixel.

Photometer for measuring the directional light distribution characteristics of sources or luminaires .

Directional light has orientation but no position, and it is commonly used to simulate distant light sources, such as the sun.

First it is necessary to define the light's position (or direction for a directional light).

Finally, in Forward rendering path, only the brightest directional light can cast shadows.

Shadow Distance is extremely important for both quality and performance of directional light shadows.

Number of cascades to use for directional light shadows.

This member has meaning only for directional light and spotlights.

Here, we used a directional light and hence the complete plane is illuminated.

A directional light emits parallel rays in one direction.

In the directional light case, step 1, the normalisation of L, should be done only once because L is the same for every vertex.

Shadow softness fade based on the distance from the camera. Directional light only.

the same is true for our directional light.

the original design dimension and shape of the main transmission gear are manufactured or repaired by a laser directional light prototype;
