XDECAL is a decal management addon that enables drag-and-drop placement of textures without requiring UV mapping. It features a dedicated placement gizmo and interactive projection capabilities with depth control, allowing decals to conform to curved hard-surface models. The tool supports converting any material or 3D object into a reusable decal template that can be pasted across scenes. The addon includes a built-in palette that reads image formats like JPG and PNG directly from local directories without pre-conversion. It provides a context popup for adjusting geometry and material settings, including procedural effects for damage, peeled paint, wear, and parallax. The package comes with a library of prototype materials, weathering textures, and over 500 included decals.
