For the past 6 weeks, I wrote a research paper about photogrammetry in Houdini and created an optimization tool/HDA for cleaning and optimizing highpoly scans to gameready assets. The tool can easily create optimized assets with UV's and baked maps within about 30min (depending on hardware ofcourse). It can also be run overnight with a PDG system through which you can process multiple scans. Something extra that was added was procedural wear on the assets.
Demo of the tool in action (total processing time about 15min)
