About this project
World-editing toolkit for Hytale — swap materials & generate shapes.
BlockMorph is a server-side Hytale plugin that gives builders two powerful tools in one UI:
Material Swap — Select a group of blocks (via Selection Tool or manual coordinates) and instantly convert their material while preserving block shape (stairs, slabs, walls, fences, roofs, doors, etc.). Pick from an auto-generated list of compatible material variants.
Shape Generator — Hold any block and generate geometric shapes: Cube, Sphere, Cylinder, Pyramid, Cone, and Torus. Adjust radius, height, size, hollow mode, and preview the result in real-time before committing. Fly around the preview freely to inspect it from every angle.
Both tools share a full undo history (up to 5 operations).
