point

 – The sampled point.

pointReference

 – The shading point in reference space. 

pointObject/Camera

 – The sampled point in object/camera space.

normal

 – The surface normal for the sampled point.

normalReferece

 – The smooth normal in reference space. 

normalCamera/Object

 – The surface normal for the sampled point in object/camera space.

bumpNormal

 – The bump normal for the sampled point.

bumpNormalCamera/Object

 – The bump normal for the sampled point in object/camera space.

gnormal

 – The geometric normal for the sampled point.

camToWorld – The transformation from camera to world space.

view_dir

 – The view direction.

frame_time

 – The current frame (image) time. 

ray_time

 – The ray time between the motion blur interval. 

facing_ratio

 – Returns a number

between 0

 and 1

 that specifies if the sampled point is facing towards or away from the camera.

material_id

 – The material ID for the sampled point.

flipped_normal

 – Specifies which side of the surface is sampled.

cameraNearClipPlane

 – The camera near clipping plane, calculated from the scene bounding box and the camera transform in the frame data. 

cameraFarClipPlane

 – The camera far clipping plane, calculated from the scene bounding box and the camera transform in the frame data. 

uvCoord – The UV coordinates for the sampled point.

rayDirection

 – Returns a vector from the sampled point to the camera position.

pixelCenter

 – The location of the pixel in the final rendered image that corresponds to the sampled point.

tangentUCamera

 – The surface tangent in the U direction for the sampled point.

tangentVCamera

 – The surface tangent in the V direction for the sampled point.

ray_depth

 – The ray depth. 

path_length

 – The path length. 

object_id

 – Returns the object ID for the object at the sampled point.

parent_object_id

 – Returns the object ID for the parent object of the sampled point.

velocity

 – The velocity of the sampled point.

speed

 – The speed of the sampled point.

random_by_renderID

 – Allows random colors or textures to be assigned to several objects according to each object's render ID.

random_by_polyShell

 – Allows random color or textures to be assigned to multiple polygon shells that have been combined into a single object.

Image Modified

 – Specifies the name of the UV channel that is used for sampling.

UV Index

 – Specifies the index of the UV channel that should be used for sampling when there is no applicable UV set name.
