In the past I've always automated exporting from Maya, 3DSMax and Photoshop, meaning I don't require artists to export from either. The artist saves the source file in the project, tools build from that to the final format for the app/game.
The more typical workflow is that artists export .JPGs or .PNGs manually from Photoshop and somewhere else save their .PSD files. Similarly with 3SDMax or Maya they'd manually export using some plugin. That seems wasteful to me and error prone. Source files get lost. Artists have to maintain multiple versions and do the export manually which seems like a huge waste of time. So, I automate it.
