The fov and fovEnd parameters set the value of the fov at the beginning and end of the shutter. FOV Motion BlurįOV motion blur is only supported with the PxrCamera projection shader. This is available in PrmanCameraSettings as 'Use Camera FOV'. If you wish to set the FOV with the material attribute, you can set the IntAttribute, eGeometryFov, to 1. By default, RfK will use the FOV from the camera's geometry.fov attribute, pushing this value onto the projection plugin's material attribute. Since Katana supplies the field of view on camera as the geometry.fov attribute rather than material, we have two ways to set FOV. In RenderMan, the FOV is set as a part of the projection plugin. If the prmanProjectionShader parameter is left empty, RfK will use the projection specified via the geometry.projection attribute on either in the CameraCreate node or Alembic_In camera. If you create custom projection plugins using C++, these will also show up in the drop down menu as long as they have Args files and are accessible via the RMAN_RIXPLUGINPATH environment variable. These attributes can be overridden locally per camera.Īll of RenderMan's projection plugins are available in the prmanProjectionShader drop down menu of PrmanCameraSettings. If camera settings are set at /root, they will be inherited by the cameras in the scene - projection parameters as well as prmanCameraStatements. If you wish to apply the same settings to multiple cameras, you can add all the camera paths to the CEL parameter. The locationPath should be either /root or a camera location. PrmanCameraSettings can be assigned per camera or to /root. This node is used to set camera options and parameters like depth of field controls, shutter timing, render clipping planes, and other projection parameters. PrmanCameraSettings needs an upstream camera or /root in the locationPath to populate the camera parameters.
