The exact workflow steps and the order in which you perform them vary. Rendering is an iterative process in which you tweak lights, textures, and cameras; adjust various scene and object settings; visualize your changes; then, when you are satisfied with the results, render your final images.
Once you have completed shading and texturing objects, adding lights, and adding renderable cameras to your scene, you can render your scene. The following workflow outlines the typical steps.
