StampIT is a Blender add-on designed to streamline the application of decals and PNGs to 3D models, using a "controller empty technique" that avoids adding extra vertices.
Compatible with both Cycles and Eevee, StampIT offers a variety of features, including stamping images and PBR materials, auto-parenting, an opacity slider, auto-resizing, and organized node groups. It eliminates the need for a shrinkwrap modifier by utilizing material coordinates for image overlay, enhancing flexibility in positioning and scaling. Additionally, StampIT supports layering images within Blender’s material editor, allowing easy adjustments and quick modifications. This method facilitates a new approach to texture painting, speeding up the creation process and improving design modularity. A unique feature of StampIT is the alpha cutout capability, enabling users to create cutout effects on models, similar to booleans with images.
