There are some guys who make alot of cash to recreate accidents for personal-injury attorneys. But the most common commercial use for Poser is to make add-ons (like the clothing, hair, poses, motion files, characters etc.) sold at this marketplace, Daz and elsewhere. These add-on items are mostly bought for peoples' personal use as hobbyists, but a small fraction of the buyers later use the products to produce images for advertising, book illustration and accident/crime scene recreation. The items (clothing, hair, poses, motion files, characters etc.) are not always made in Poser, so to make money you also need to be an expert in 3D-modelling apps.
