Engon is an open-source asset browser extension designed to manage and spawn curated collections of models, materials, and geometry nodes. It acts as the core management tool for polygoniq's .paq formatted asset libraries, such as botaniq, traffiq, and materialiq. The tool includes features for scattering instances, snapping assets to the ground plane, and randomizing the scale and rotation of selected items to add variation to scenes. Users can filter assets by tags, convert between linked and editable geometry states, and use a migration tool to update assets in older scenes.
