Lights

When you add a new 3D Scene, there's a default light setup already present for you.

There are 3 types of lights in GMetri - Ambient, Point and Directional.

Ambient Light

Ambient Light is a lighting technique used in an experience to provide an overall level of illumination to a scene or environment. It's a type of indirect lighting that simulates the light that is reflected or scattered from surfaces in a scene, such as walls or objects.

Ambient Light helps to create a more realistic and immersive environment, and it can be adjusted to different levels to change the mood and tone of the scene. It's also useful for providing a base level of illumination when other lighting sources, such as directional or point lights, are not sufficient.

In any experience, ambient light can be set and adjusted using tools and controls provided by the platform or development environment.

Point Light

Point lights are often used in combination with other lighting techniques, such as ambient light or directional light, to create a more complex and realistic lighting setup. They can be placed in specific locations within a scene or environment to highlight or illuminate certain objects or areas.

In an experience, point lights can be adjusted and customized using tools and controls provided by the platform or development environment. The intensity, color, and range of the light can all be adjusted to achieve the desired effect. Additionally, multiple point lights can be used within a scene to create more complex lighting setups and add depth and dimensionality to the environment.

Directional Light

Directional light is characterized by its constant intensity and parallel light rays that do not diminish with distance. It's particularly useful for creating dynamic and realistic outdoor environments, such as landscapes or cityscapes.

In an experience, directional light can be customized and adjusted using tools and controls provided by the platform or development environment. The color, intensity, and direction of the light can all be modified to achieve the desired effect. Additionally, multiple directional lights can be used within a scene to create more complex lighting setups and add depth and dimensionality to the environment.

The right panel allows you to manage the lighting in your experience. You can choose the lighting type, color, intensity, and target object from this panel.

Light adjustment

You can add a light to your experience by adding an element and choosing the 'Light' option under 3D elements.

Adding light into your experience.

Here's an example of how the point light, directional light works. Walk towards the element Sphere and Cube to read through what they do.

An experience will be set with a default set of lighting which will include ambient light.
