Enable Antialiasing
Enables antialiasing for the Auxiliary Canvases.
 
Note:
When turning on Enable Antialiasing for the Auxiliary Canvases note the following:
 
 
Depth
A framebuffer that contains the depth of the hit point along the (negative) z-coordinate in camera space. The depth is zero at the camera position and extends positive into the scene. This channel is also known as z-depth in other packages and mostly used for compositing.
 
Distance
A framebuffer that contains the distance between the camera and the hit point measured in camera space. The distance is zero at the camera position and extends positive into the scene.
 
Normal
A framebuffer that contains the normalized surface shading normal in camera space excluding any effects from normal perturbation functions.
 
Object Id
A framebuffer that contains a single color for each geometry. Each shape node has an attribute named Object Id. The integer value set in this attribute defines the color the object gets in the framebuffer. The color is the same in every frame over an animation.
 
Material Id
A framebuffer that contains an internal implementation-specific Id of the surface material. This Id can be used to identify regions in the image that show the same material or regions without material, in particular the background, where the Id is zero. Because the material id is calculated by a random integer number at the beginning of the rendering, the color may vary in every frame over an animation.
