 Qwen Multiangle Lightning Node for ComfyUI
-Final Corrected Version: 
-1. Scene Lock prioritized in global prompt.
-2. Light Position prioritized within lighting description.
-3. Pure light source (No shadows).
-4. Full UI features and registration.
+Verified Stable Version: 
+- Explicit interval checks for elevation.
+- Light Position Priority.
+- No Shadows.
