PrmanCameraSettings needs an initial camera upstream in order to populate the camera parameters. |
This node is used to set camera options and parameters like depth of field controls, shutter timing, render clipping planes, and specifying a projection type.
RenderMan comes with some built-in camera projections: perspective, orthographic, sphere, cylinder, and torus. Additionally, you can create custom projection plugins using C++. Both types of projections are available in RenderMan for Katana.
Built-in camera projection plugins are available in the camera settings node itself.
The default projection type will use the projection specified either in the CameraCreate node or Alembic_In camera.
Custom Projection plugins, such as PxrCamera, are created with a Material or PrmanShadingNode and assigned to /root with a MaterialAssign node. Just like projection modifiers, only one custom projection plugin can be used at a time in conjunction with a default projection.
