Hudinator: Sci-Fi Ui Visualizer is a Blender add-on from PIXLOR for building sci-fi styled HUD panels in a quick and easy way. It draws on a database of over 140 elements ready to import into a project. Sixty of these are built with the Geometry Nodes system so they can be edited, while the remaining 83 are basic decals. Combining and editing individual elements lets you create simple shapes or complex structures.
Each non-decal object carries its own settings window split into three sections. Settings covers the shape and differs from element to element; Material lists the materials assigned to the object; and Transform handles animation, including different types of circular object animation. The same material is assigned to every imported object, so editing it in one place updates all objects sharing it. A duplication button makes a material local to one object, and you can swap in your own materials or restore the default.
Objects can be duplicated freely, with each copy inheriting the original's shape, materials and animation until you make it unique. Hudinator works in both EEVEE and Cycles, and a "Place at" checkbox controls where an object is placed. It is released under the GPL license.
