Overview
Taking real CAD geometry and getting it renderable without melting your computer can be a headache. For Mk11, I wrote a CLI tool (step-to-usd) that meshes STEP models for a film and VFX pipeline. Along with standard surface meshes, the program generates wireframe an sketch curves so I could achieve a “draftsman’s aesthetic”. Read Curves, B-Reps, & Chaos for all the details. To speed up look development (and manufacturing), I put together an OSL shader library. The painting process is covered in The Mk11 Livery.
