Darrel, I feel ya, about customer expectations. Even after all our combined years of experience, and pulling each other up the learning curve, rendering still takes considerable time. Like on this scene, I added four pieces of large equipment (painstakingly modeled and texture mapped), under-the-counter CPUs, and keyboards, all with cabling. And the project's still in the bidding phase. On the one hand, it's a lot of work upfront, and on the other, when we do sell the project, pulling construction prints will be easy, along with exploded-view assembly diagrams. It's a good thing I like making these pretty pictures!
This one was rendered to a 2000x3140 png file, still under Lightworks. I gotta say, 64-bit rules, because adding all the equipment barely slowed the process, plus, I was working on editing previous images in Photoshop, and preparing the presentation brochure, all at the same time. Cool.
