I have some good experience with this. If you look at my portfolio, you might notice there is an indoor render. That is inside a game engiene, so if you are looking for 3d models rendered inside a 3D application, the results would be a lot better and way more realistic. I hope I can help you with this. I do have experience as I used to work with this on my collage last year. Feel free to contact me so we can further discuss this!
