The editor can load and preview particle effects but may not be fully functional for all PSB files. Contributions and testing welcome.\n\n\u003e **Note:** This project was developed with significant AI assistance (Claude by Anthropic). All code has been reviewed and validated by the project maintainer, but AI-generated code may contain subtle issues. Contributions and reviews are welcome.\n\nPart of the [LU-Rebuilt](https://github.com/LU-Rebuilt) project.\n\n## Usage\n\n```\npsb_editor [file.psb]\n```\n\n**Features:**\n- Real-time particle simulation using PSB emitter parameters (colors, velocities, sizes, gravity, spin)\n- Textured billboarded quads with DDS texture loading from client resources\n- Sprite atlas UV rect extraction for texture page sub-regions\n- Color lifecycle: start, middle, end color lerp\n- Blend mode support: additive, screen, multiply, alpha blend\n- Property tree showing all PSB fields organized by section (colors with swatches, timing, velocity, size, rotation, textures with UV rects)\n- Adjustable playback speed slider (0.1x - 10x)\n- Adjustable emission rate slider (0.1x - 20x)\n- Looping playback (burst and continuous emitters)\n- Orbit camera with mouse drag and scroll zoom\n\n**Keyboard shortcuts:**\n- `Ctrl+O` — Open file\n- `Space` — Play/Pause\n- `Ctrl+R` — Restart emitter\n- `Ctrl+Shift+R` — Set client root\n\n**Setup:** Set the client root to the game's install directory (containing `res/`) so the editor can find texture pages in `res/forkp/textures/dds/`. The editor auto-detects the root when opening PSB files from within a client directory.\n\n## Building\n\n```bash\ncmake -B build\ncmake --build build -j$(nproc)\n```\n\nFor local development:\n\n```bash\ncmake -B build -DFETCHCONTENT_SOURCE_DIR_LU_ASSETS=/path/to/local/lu-assets \\\n               -DFETCHCONTENT_SOURCE_DIR_TOOL_COMMON=/path/to/local/tool-common\n```\n\n## Acknowledgments\n\nFormat parsers built from:\n- **Ghidra reverse engineering** of the original LEGO Universe client binary — PSB binary format, ForkParticle emitter fields\n\n## License\n\n[GNU Affero General Public License v3.0](https://www.gnu.org/licenses/agpl-3.0.html) (AGPLv3)\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flu-rebuilt%2Fpsb-editor","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flu-rebuilt%2Fpsb-editor","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flu-rebuilt%2Fpsb-editor/lists"}
