Updated the description of the RBG Smart Seed Variance node to clarify its functionality and added details about generative models affected by seed variance and diversity bias.
RBG Smart Seed Variance — Minor fixes 2.2.1
Minor text updates and small fixes
Previous major updates
- Add Krea2 (SingleStream) model type with band-aware noise handling across
the 12-layer MMDiT tap stack, including a dedicated base-embedding
rebalance pass to boost expression, attention detail and prompt following.
- Add ERNIE-Image to model-specific adjustment presets, alongside
refined multipliers for Flux, Chroma HD, SDXL and Wan2.2.
- Add interactive token protection inspector (JS): click-to-toggle individual
tokens directly on a live visualisation of the protection mask, replacing
manual range typing as the primary workflow.
- Add "Custom Regions" and "Random Regions" protect modes — custom accepts
explicit token/range syntax (e.g. "0-5,15-20"), random seeds a procedural
protection mask.
- Add live protection mask feedback from backend to frontend via onExecuted,
so the inspector reflects the actual tokens used in the last run rather
than a static preview.
- Add Variance Schedule (Composition Lock 🔒) — control how noise intensity
changes across the sampling timeline with 5 modes: constant, decreasing
(fade out), step_cutoff (hard switch at a step), hard_lock (zero variance
until cutoff), and tiered_release (multi-phase staged unlock)
- Add cutoff_step, total_steps, and cutoff_strength controls — map a step
number to a percentage of the sampling timeline and set the noise
multiplier applied after the cutoff point, so composition can be locked
early while detail variance continues later.
- Expand direction shift library from the original artistic set to 26+
patterns, including Face-Variance Expansion, Visceral Expression & Grit
(Krea2-tuned), Semantic Drift, Structural Lock, Cinematic Framing, Texture
Lift, Landscape Depth, Group Diversity, Expression Variance, Motion Blur,
Microscopic, Cosmic, and Bone Anatomical Coherence.
- Add dynamic widget visibility — protect_regions field now shows/hides
automatically based on the selected protect_mode.
- Fix word-index vs BPE-index mismatch in token protection by adding
bidirectional BPE-to-word mapping, so protected ranges align correctly
with actual tokenizer output instead of word-level approximations.
