Krea2 RAW Turbo High-Low Noise Sampling

This is an advanced final rendering workflow based on Krea2 RAW, Krea2 Turbo, and SplitSigmas high-low noise segmentation.

The process first uses the Krea2 RAW model to handle the high-noise phase for initial drafting, establishing overall composition, main structure, spatial relationships, and large-scale forms. Then, SplitSigmas is used to divide the complete sigma sequence into high-noise and low-noise segments, allowing RAW to process the high-noise structure and Turbo to take over low-noise convergence, thereby forming a more controllable RAW-Turbo relay sampling chain.

Unlike a conventional two-stage RAW to Turbo workflow, this process does not simply run RAW first and then Turbo. Instead, it explicitly separates the sampling noise intervals: RAW is responsible for earlier and coarser structure generation, while Turbo handles later-stage convergence, detail refinement, and image stabilization. This allows for more precise control over composition, detail generation, convergence speed, and the final rendering texture.

After the high-low noise relay, the process incorporates latent upscaling, Turbo low re-rendering refinement, 1.25× image upscaling, VAE re-encoding, and final Turbo convergence. This makes the output results more suitable than a standard single-pass Krea2 Turbo for creating high-definition posters, widescreen covers, and complex fantasy illustrations.

It is suitable for Krea2 advanced sampling tests, RAW/Turbo relay rendering, widescreen fantasy posters, cinematic world-building illustrations, complex scene generation, detail enhancement, and high-quality final rendering pipeline research.
