I want to set up a model village for the background in a series of tabletop photos. I would prefer not to make and paint styrofoam models and so when I came across Photobash and Turbosquid by Shutterstock they looked promising. I am not quite sure how satisfactory these 3D models - I see on their sites how to pay - but the sites seem to assume the consumer knows what the next steps are but I don't.

Does anyone have any experience with purchasing 3D models? Thank you
