Optimized for blocks that carry millions of triangles. A full walkthrough: preparing City Sample blocks, cleaning them up in Houdini, and building the whole structure with the updated generator - from an empty project to a baked Blueprint.
Made with AI: the entire code of this generator was written by Claude Code, the AI assistant from Anthropic. I decided what the tool had to do and tested every step in Houdini and Unreal - the AI wrote the code.
