Trimsheet Express is an add-on that simplifies the creation and baking of trimsheets directly within Blender. The workflow involves creating a base plane, defining the sheet structure by manipulating faces in Edit mode, and assigning source materials to individual sections through a dedicated panel. The tool then automatically packs the selected materials, including all texture channels, into a unified trimsheet layout. It includes integrated baking features to handle complex material setups and supports custom texture output resolutions. The add-on is compatible with Principled, Glossy, Diffuse, and Transparent shader output nodes. Users can scale and transform each material section independently, view live updates in Edit mode, and batch export the final trimsheet textures with custom naming conventions.
