<extra>/<technique profile="modo401">/<param> Elements
- Category: (core) Camera (See list of specification categories)
- Introduction: Describes custom cameras, include the specialized spherical camera sub-type supported by modo 401.
Concepts
- The modo render engine provides a general purpose camera, including perspective and orthographic optics as specified by the common COLLADA technique, as well as a specialized spherical camera.

Details
- The target-related params should only appear if the initial targetID param is present, as those channels are only available for cameras which have a target set. The target-related channels are added during scene load only when a targetID is found.
