Version 4.11.19
Optimize startup performance with lazy loading and async checks
Engine node optimizations:
- Replace heavy engine imports in INPUT_TYPES with file-reading-only model discovery
- Remove blocking module loads from node initialization
- Reconstruct discovery logic for all 7 engine nodes: VibeVoice, F5-TTS, Higgs, ChatterBox, ChatterBox 23-Lang, IndexTTS, RVC
- Each engine now scans model folders without importing engine modules
Voice discovery and dependency improvements:
- Implement persistent voice character discovery cache in .cache folder
- Add background refresh thread for cache updates
- Move dependency checking to async background thread (2-second delay)
- Prevent blocking initialization on startup
- Print diagnostic messages after ComfyUI loads
