It is the stage of production of 3D renderings and processing through the specific programs. Often this stage is done after the export the image from rendering.
The process of Post Production is the process of the final output of the 3D rendering where we change colors and adding shadows. It is a very important process for every 3d rendering, especially for the exterior 3d rendering.
One of the most important features is the speed of work by reducing the time of rendering of some elements such as trees, grass, lights, general location, background, and objects. It also helps in the process of color contrast, brightness, shading and error correction
