Vertex Light Settings

This section describes the basics of creating and configuring vertex lights.

Vertex lights

Vertex lights illuminate the vertices of polygon models.

The following three light settings can be made for vertex lights under CreativeStudio.

Light Types Description
Directional light This type of light shines uniformly from an infinite distance, like the sun.
You can set the angle.
Point Light This type of light shines conically from a single point.
You can set the distance attenuation.
Spot Light This type of light shines conically from a single point.
You can set the distance attenuation and angular (conical) attenuation.

This section describes how to create a vertex light by loading sample data and then describes the basics of how to configure lights by type.

Loading Models

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

This example is based on a spherical model that uses lambert.

Reference:
The size and position of the sample sphere being used are given below.
Here, Maya is being used as the 3DCG tool. (Defaults are used for all tool settings.)

Material Panel Settings

You can use the CreativeStudio material Properties panel to configure a material to be lit solely by vertex lights.

Select a material displayed in the Contents panel to open the material Properties panel.

Changing lighting settings

Under Lighting on the material Properties panel, select Enable vertex lighting.

Rendering settings

Texture Combiner Settings

Configure the settings for combiner 0 on the material panel as follows.

For details on texture combiners, click here.

This configures the material to only be lit by vertex lights.
With this configuration, the B: Source 1 and C: Source 2 settings are not used.

Creating and configuring vertex lights

On the CreativeStudio menu, select CreateLightVertex Light to create a vertex light.

Creating a vertex light

Opening the Light Panel

Click a light displayed in the Contents panel to open the light Properties panel.

Adjusting the Ambient Color

On the light Properties panel, under Category, check Ambient color.

Editing light panel properties

Selecting Ambient color displays ambient color settings on the light Properties panel.

Change the light panel ambient color settings to the values below.

Note: Left-clicking on the color thumbnail displays a Color Picker pop-up that allows you to set the color.

These settings produce the following preview image.

Light Types and Settings

This section describes how to switch between the three types of configurable vertex lights and their basic settings.

The initial light type setting in the light panel is for directional light.

Directional light (parallel light source)

A directional light shines a uniform light from an infinite distance, like the sun. You can set the angle.

Selecting the Light Type

Under General on the light Properties panel, select Directional light.

Changing the Light Direction

Change the direction on the light panel to change how the model is lit.

Point lights

A point light shines radially from a single point. You can set the distance attenuation.

Setting Distance Attenuation

You can also set the distance attenuation for a point light on the light panel.

Distance attenuation is disabled by default, so be sure to select this option and enable it.

Sample Configuration

Changing the Light Position

Set the position of the light created under Position on the light Properties panel.

Changing the Light Position

The same point light as shown in Figure 2 can be created with the above settings.

You can check how point light attenuation changes in the preview when changing the distance attenuation by some other means, such as using a slider.

Spot Light

A spot light shines conically from a single point. You can set the distance attenuation and angular attenuation.

Changing the Light Direction

You can change the light direction on the light panel.

Setting Distance Attenuation

You can also set the distance and angular attenuation for a spotlight on the light Properties panel.

Distance attenuation is disabled by default, so be sure to select this option and enable it.

Spotlight distance attenuation

Angular attenuation sets how the light attenuates based on the angle the light is pointing.
