LucasDower/ObjToSchematic ? reverse-engineered prompt

Build me a web app that lets me upload a Wavefront .obj 3D model, preview it in the browser, and convert it into a Minecraft build I can download as .schematic, .litematic, .schem, or .nbt.

I want it to feel like a simple visual editor, not a technical converter. Let me rotate the model, tweak how it gets turned into blocks, adjust materials and textures, choose the output size, and see a live preview of the voxelized result before exporting. It should support solid and textured materials, handle transparency, and let me pick a block palette for the Minecraft blocks used in the final structure.

Make the interface clean and easy to understand, with clear steps for import, voxelizing, assigning blocks, and export. If you need to look up current docs online for the file formats, feel free to.
