Lightbox Shader Examples

To help you in creating custom Lightbox shaders, examples are available in the /opt/Autodesk/presets/<application_version>/action/lightbox/EXAMPLES.

The following example Lightbox shaders are available:

GGXIBLExample

Similar to GGXMaterial, but it doesn't hijack the Material node, and all controls are present in the Lightbox itself. Also, it doesn't support object texture and only a BaseColor which is set in the Lightbox itself.

GGXMaterial

This shader performs a rendering of the scene using a physically based shading algorithm which requires three distinct values from each material in the scene: the Specular, Metallic, and Roughness component values. These components are not available natively in the Material settings, so they are mapped as followed in the GGXMaterial Lightbox shader: Specular Red Channel for the Specular value, the Specular Green Channel for the Metallic value, and the Shine parameter to define the Roughness.

LightboxAPISimple

This shader shows all possible API calls to the Lightbox API and shows a simple decay example using vertex and light position.

LightboxBasics

This is the most basic usage of Lightbox, only applying a Gain without having to use the API at all.

PhysicallyBasedIBL

Shows how to use the Shader Physically Based mode API with Lightbox; in this case, it is computing the IBL based on these values.

SimpleLight

This is an example of re-creating an Action light in Lightbox using the API.
