Anima → Krea2 → SeedVR2 | Three-Stage Anime Pipeline (txt2img → repaint → upscale)

A single-queue workflow that combines Anima's tag-based anime generation with Krea2 Turbo's natural-language refinement, finished with SeedVR2 upscaling.

What it does

1. Anima base (txt2img) — Anima base v10 generates the composition from Danbooru-style tag/nature language prompts. Full LoRA support via Power Lora Loader.

2. Krea2 repaint (img2img) — The base image is passed straight into Krea2 Turbo through the shared qwen_image_vae (no quality loss from format round-trips). 8 steps / CFG 1, denoise 0.3 by default:

   • 0.2–0.35 → light polish, keeps Anima's composition and linework

   • 0.4–0.55 → stronger Krea2 restyling, more detail repainted

3. SeedVR2 upscale — lanczos ×0.7 pre-scale, then SeedVR2 7B upscales to 2000px.

Features

• Separate LoRA loaders and prompts per model — tag prompts for Anima, natural language for Krea2. Describe the same scene on both sides for best consistency.

• Shared seed — one Seed Generator feeds both KSamplers, so one roll syncs the whole chain. Set it to fixed to reproduce and iterate.

• One-click upscale bypass — Fast Groups Bypasser toggles the SeedVR2 group for fast preview rounds (saves VRAM too).

• Built-in A/B comparer — slide between the Anima base and Krea2 repaint.

• Intermediate saves at every stage (base / repaint / final), core SaveImage nodes only — workflow embeds in PNG metadata as usual.
