Z-Image-Turbo Custom Nodes - Real RF Samplers
ComfyUI's built-in euler/euler_ancestral use wrong formulation for Z-Image-Turbo.
This fixes it with proper rectified-flow samplers.
What you get:
- euler_flow - clean interpolation, no sigma division bugs
- Linear schedulers (critical for Z-Image-Turbo bf16)
- Higher-order variants (midpoint/heun)
- Presets for 8-9 step workflows
Settings:
- 8-9 steps
- CFG 1.0
- eta 0.0 (sharp) or 0.1-0.2 (slight variation)
Sharper faces, better details, no late-step artifacts.
Flux Klein image edit settings:
replace the sigma with 🎯 Flow Match Presets (choose the schnell preset) connect the height and width.
use âš¡ Z-Image Flow Sampler set eta=0-0.15 , s_noise= 1.00-1.50.

Note: midpoint flow is not functioning for now; will update soon!
