Smartify Nodes is an asset library of node groups designed to add environmental effects to existing PBR materials. Users can drag and drop effects like moss, snow, dust, sand, edge-wear, and water puddles directly onto materials. The system includes smart masks for facing, location, ambient occlusion, edges, and leaking, alongside utilities for anti-tiling and parallax mapping. Effects can be manually controlled using vertex or texture painting to force or mask specific areas. The node setups feature world and object-space sliders to adapt effects to different scales, and all nodes include height inputs and outputs for displacement integration.
