Baking and Viewer application. Fairly affordable as these things go, and you can upload the finished viewer to Artstation or elsewhere. And there's a free 30-day trial, which is what I'm using atm (guess what I'm buying with my tax return this year!)
Example of usefulness - you can run all your bakes at once, it's fricking ridicoulously fast, they're anti-aliased, and it drops them into a named multilayer PSD for you. Plus you can preview them on your low poly, as well as adjust and preview in near real-time your offset for cage/ray settings. For my ships with their extremely bake-heavy pipeline, it's a godsend.
Got a 3-module ship textured in one day. BOOM.
