Commonly, 3D geometry with transparency is rendered by blending (using alpha compositing) all surfaces into a single buffer (think of this as a canvas).Each surface occludes existing color and adds some of its own color depending on its alpha value, a ratio of light transmittance.
Checkerboard rendering or sparse rendering, [1] also known as checkerboarding for short, is a 3D computer graphics rendering technique, ...
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite.

Cryptomatte images can be created by several 3D graphic programs like Blender, [2] Autodesk Maya, [3] Autodesk 3ds Max [4] or Houdini [5] and are usually exported using the OpenEXR file format. Whether a program is able to generate a cryptomatte or not is determined by the render engine being used.
One key disadvantage of deferred rendering is the inability to handle transparency within the algorithm, although this problem is a generic one in Z-buffered scenes and it tends to be handled by delaying and sorting the rendering of transparent portions of the scene. [6]
Depth peeling works by rendering the image multiple times. [1] Depth peeling uses two Z buffers, one that works conventionally, and one that is not modified, and sets the minimum distance at which a fragment can be drawn without being discarded. For each pass, the previous pass' conventional Z-buffer is used as the minimal Z-buffer, so each ...
