Six Krea2 workflows built around one idea — draft with RAW, finish with Turbo, and never let a single sampler do both jobs.

The core mechanism

RAW produces structure. Turbo produces finish. Running them as one pass forces a compromise; running
them as two passes lets each do what it is good at.

The six workflows are variations on that split:

# Workflow Focus
1 Dual-phase finalize The base two-pass chain
2 Merged model A single merged checkpoint equivalent
3 4K/6K upscale chain Mega-resolution output
4 New sampler engine Clownshark × WanVAE texture variant
5 Texture unlock core Control-enhanced variant
6 RAW base + Turbo chain Reference configuration

The upscale chain

4K and 6K output from a two-pass chain is where the order of operations shows. Upscaling before the
Turbo pass preserves texture; upscaling after it produces a smooth, slightly plastic 6K image.
