This collection contains 3D models and rigs extracted from Valve's Portal and Portal 2, prepared for use in Blender. The pack includes various props and characters, including portal guns and personality cores from fan-made game remakes. The rigs utilize custom bone drivers to provide functionality directly in the viewport. Users can access options on the root or base bones to switch between RTX material variants, toggle parenting constraints, and change textures, such as swapping portal gun colors or applying dirt overlays.
