Hemispherical Light Settings

This page describes the basics of creating and setting hemispherical lights.

Hemispherical Lights

Hemispherical lights are ambient lights where two-color interpolation is made based on two colors (top and bottom).

The top is called the sky color, and the bottom is called the ground color.

Loading Models

On the CreativeStudio menu, select FileOpenIntermediate file to load the model intermediate file.

In this example, we describe a spherical model that uses Lambert shading.

Changing the Sky Color Weight

Change the weight of the sky color to adjust the relative strengths of the sky and ground colors.

Changing the Sky Color Weight

Setting the sky color weight closer to 1 makes the sky color stronger, and setting the weight closer to 0 makes the ground color stronger.

In this example, we set the sky color to 1, making the sky color stronger as shown below.
