Tutorial: Photogrammetry for Production Artists
The workshop, which is targeted at users new to photogrammetry work, provides over four hours of video training in software including Metashape, Lightroom, ZBrush, Modo, Marmoset Toolbag and Photoshop.
Create production-quality scans of real-world objects to use as props in games and VFX
In the workshop, Crossland reveals how to create 3D scans of props suitable for use in production in games or visual effects using a photogrammetry-based workflow, using a hiking boot as an example.
He discusses different ways to create low, medium and high-range scans, and how a high-quality scan can be used as the baseline for a production asset.
The tutorial covers Crossland’s complete workflow, beginning with capturing the source photos of the boot from which the scan will be generated, processing them in Lightroom, and generating the scan in Metashape.
He then discusses how to clean up and retopologise the raw scan to create a clean, high-poly model as well as a low-poly version with UVs ready for texturing in Marmoset Toolbag.
The final chapter of the tutorial covers how to create display renders of the scanned asset.
Viewers of the workshop can download supporting files including Crossland’s ZBrush .ztl file, Modo scene file, Marmoset Toolbag scene file, and the final Photoshop composite.
