The Arnold tab includes all the Arnold parameters for a perspective camera. For other Arnold camera types, you can use the Override Camera section to use a different camera and edit its parameters.

Camera

• Exposure
• Radial Distortion
• Radial Distortion Type
• Lens Tilt Angle
• Lens Shift
• Filter Map For a filter map, create an Arnold MaterialBuilder, add a Camera Output node, and connect a shader to the filtermap port.
• UV Remap For a uv remap, create an Arnold MaterialBuilder, add a Camera Output node, and connect a shader to the uv_remap port.

Motion Blur

Motion blur uses the Shutter Open and Shutter Close from the Sampling tab.

• Shutter Filter
• Rolling Shutter
• Rolling Shutter Duration

Depth of Field

• Focus Distance is on the Sampling tab.
• Aperture Blades
• Aperture Rotation
• Aperture Blade Curvature
• Aperture Blades

• Cylindrical camera
