I got a chance to use some 3D models of Star Wars spaceships in point of sale material for a stall at Comic Con in Sydney this year:
The assets in the posters and banners were the 3D models of the X-wing, Millennium Falcon & Tie fighters, Planets and star fields made in Adobe Photoshop from scratch. and text, with all the assets put together in InDesign for output to PDF.
Tons of fun to do, and a quick job to turn around for my client.
