Extreme PBR Nexus is a material manager and workflow addon for Blender that provides access to a library of over 1800 materials. It features tools for texture painting, allowing users to blend between multiple materials directly on meshes using masks. The addon includes specific material generators for multilayered car paint and automatically animated water surfaces.

The toolset offers an FX layer system for adding weathering effects like worn edges, scratches, and dust. Workflow utilities include Z-axis material blending, visual texture mapping in the 3D viewport, and an anti-tile system to reduce visible texture repetition. Users can apply non-destructive micro-displacement and bake mixed materials into game-ready texture maps. The addon integrates with Blender's native Asset Browser and supports both Cycles and EEVEE.
