- Category: (core) Lighting (See list of specification categories)
- Introduction: Describes custom light settings, including various light sub-types supported by modo 401.
Concepts
- The modo render engine provides a general purpose collection of light settings and light sub-types, including both the basic directional, point, and spot lights specified by the common COLLADA technique, as well as more specialized light sub-types such as area lights and physically correct sunlights.

Details
- modo 401 supports the following light sub-types, as indicated by the initial param element identified by the "lightType" sid, as shown in the example later in this article:
- area_light
- cylinder_light
- dome_light
- photometric_light
- point_light
- spot_light
- sun_light
