3D renders can often have problems that are much easier to fix in post, rather than spend time and money re-adjusting, and then re-rendering the image. Especially when you have a series of images you're working with. Matching colors to proper callouts, matching contrast and tone of the overall family, adding or removing light sources, repairing topology (surface) tears and breaks, removing unwanted reflections or anomalies, and compositing options from other renders. These things can take your 3D rendered images to the next level.

Unwanted
Reflections
This set of images had the tracks reflecting up onto the main body. Client wanted them removed, along with some offensive highlights. So rather than re-rendering all 20 images, we retouched each image as needed. And, of course, we adjusted and matched color as a family.
