Inputs (17)
| Name | Type | Default | Description |
|---|---|---|---|
| conditioning | CONDITIONING | — | |
| variance_preset | COMBO | 🌿 Balanced | Select variance intensity level. Higher = more diverse outputs but less prompt adherence. |
| fine_tune_variance | INT | 500–100 | Fine-tune variance (0-100%). Only used when preset is 'Custom'. |
| model_type | COMBO | ⚡ Z-Image Turbo | Select your model for optimized settings. |
| fade_curve | COMBO | Instant | How noise fades spatially across the embedding. |
| noise_injection | COMBO | Beginning Steps | When to apply noise during generation. Beginning Steps = more composition variety, Ending Steps = more detail variety. |
| protect_mode | COMBO | 🚫 None | Protection mode: use preset regions, define custom token ranges, or protect random tokens. |
| protect_regions | STRING | Custom protection regions (e.g., '0-5,15-20'). Only used when mode is 'Custom Regions'. Format: single tokens (5) or ranges (0-5), comma-separated. | |
| direction_shift | COMBO | 🚫 None | Apply directional bias to embeddings instead of pure random noise. Creates predictable artistic shifts. |
| shift_strength | INT | 1000–200 | Strength of the direction shift effect (0-200%). 100% = default, 0% = disabled, 200% = double strength. |
| variance_schedule | COMBO | constant | Composition Lock 🔒: Control how variance changes over time. 'constant'=standard, 'decreasing'=fade out, 'step_cutoff'=block switch, 'hard_lock'=zero variance until step, 'tiered_release'=multi-phase unlock. |
| cutoff_step | INT | 80–100 | The step number where the cutoff or fade ends. (e.g. if you like composition at step 8, set this to 8). |
| total_steps | INT | 201–100 | Estimate of total sampling steps. Required to map 'cutoff_step' to a timeline percentage. |
| cutoff_strength | FLOAT | 0.00–1 | The noise intensity multiplier after the cutoff step. 0.0 = no noise (lock), 1.0 = full noise. |
| seed | INT | 00–18446744073709550000 | Seed for noise generation. Different seeds = different variance patterns. |
| target_vibeopt | CONDITIONING | Optional: Connect a conditioning to steer variance direction. The node computes a normalised per-token direction vector from source → target, then blends it with your chosen direction_shift pattern. Both work together — the vibe sets the direction, the pattern adds texture. Multi-chunk targets are matched chunk-for-chunk with the source. Use vibe_blend to control how strongly the target steers the output. | |
| vibe_blendopt | FLOAT | 0.500–1 | Controls the mix between target_vibe direction and your direction_shift pattern. 0.0 — direction_shift pattern only, target_vibe has no influence 0.5 — equal blend of vibe direction and pattern (default) 1.0 — pure vibe steering, direction_shift pattern silent Has no effect when target_vibe is not connected. |
