Cw Shader Buddy is a Blender addon that provides tools for managing images and materials in your scenes. It adds a sidebar panel to the Shader Editor, Image Editor, Compositor, UV Editor and Geometry Nodes Editor, giving you a place to overview images, assign bitmaps to shaders, and select objects based on their assigned textures or materials.
The image browser shows thumbnail previews at adjustable sizes, with Object and Scene view modes and filters for Packed, Linked or Issues such as missing, unused, dirty or brush-risk images. Multi-term search matches names or file extensions, and image usage is listed across materials, world, line style, compositor, grease pencil, brushes, modifiers, geometry nodes, camera backgrounds and image empties. You can display an image in the Image or UV Editor with one click and edit it in an external editor with automatic reload on save.
A material browser lists materials with their object assignments and supports quick selection, filtering and per-object or global replacement. Batch Rename covers images, materials, node groups, objects, collections and more, with Find & Replace, regular expressions and optional file rename on disk.
