During May 2025, Sage Nussbaum enhanced the gautschr/3D-modelling repository by delivering three features that improved asset workflows and repository maintainability. Sage updated the St. Gallus Kirche project with new 3D model assets, a thumbnail, and supporting PDF documentation, integrating these through JSON-driven configuration updates to ensure accurate presentation. To streamline asset onboarding, Sage implemented a 3D model upload capability, enabling efficient management of new assets. Additionally, repository hygiene was improved by introducing a targeted .gitignore, reducing untracked file noise. The work demonstrated practical application of Git, JSON configuration, and asset pipeline management, reflecting a focused and maintainable engineering approach.
