The layout, module toggles and general feel of V1 are still there, but the main generation path is now shorter, cleaner and built around a single sampler.The separate second pass is gone, RES4LYF is no longer required, resolution selection is easier, and the new sampler gives you simple presets while still allowing full manual control.<h3 id="workflow-files">Workflow Files</h3>The download includes both the JSON workflow and a PNG workflow image.Use the PNG version if you want ComfyUI to restore the original node layout, group positions and visual formatting.<hr /><h3 id="what-changed-in-v2.0">What Changed in V2.0</h3>New Sampler: CyberKrea Sampler<code>ClownsharKSampler_Beta</code> and the RES4LYF sampling chain are gone.Sampling now runs through CyberKrea Sampler, a compact sampler designed specifically around Krea 2 Turbo.It includes three calibrated presets:<ul><li><code>fast</code></li><li><code>balanced</code></li><li><code>quality</code></li></ul>Selecting a preset automatically fills in the sampler settings. After that, you can still adjust any individual value manually.The sampler exposes controls for:<ul><li><code>restart_frac</code> and <code>sigma_r</code> — internal restart/detail recovery</li><li><code>plunge</code> — locks the main composition before the restart focuses more on texture and detail</li><li><code>detail</code> — adjusts fine-detail emphasis</li><li><code>eta0</code> and <code>sigma_gate</code> — gated ancestral noise</li><li><code>contraction</code> — pulls the starting noise toward the photo manifold</li><li>selectable live preview methods</li></ul>The restart stage is handled inside the sampler instead of requiring a completely separate second sampling chain.The optional VAE input can also decode a preview thumbnail directly on the sampler node without affecting the LATENT output.CyberKrea Sampler: <a target="_blank" rel="ugc" href="https://github.com/cyberdeliaAI/ComfyUI-CyberKrea-Sampler">https://github.com/cyberdeliaAI/ComfyUI-CyberKrea-Sampler</a><hr />New Latent Node: CyberKrea Empty LatentNo more manually typing width and height.Choose a size tier:<ul><li>S</li><li>M</li><li>L</li><li>XL</li></ul>The resolution dropdown then filters down to matching dimensions and aspect ratios.The workflow ships with:XL — 1184 × 1776 (2:3)<hr />The 2nd Pass Group Is GoneV1 used a separate optional second sampler and latent path for additional detail recovery.V2.0 moves that functionality into the restart stage of CyberKrea Sampler.This removes the extra sampler, extra latent hop and another set of settings that previously needed to stay synchronized.The result is a simpler generation path with fewer nodes and fewer opportunities for settings or seeds to drift between passes.<hr />RES4LYF Is No Longer RequiredV1 used RES4LYF for <code>ClownsharKSampler_Beta</code>.V2.0 does not use RES4LYF anywhere in the workflow.You can leave it installed if you use it for other workflows, but CyberRealistic Krea 2 Workflow V2.0 does not require it.<hr />Negative Prompt HandlingThe <code>negative</code> conditioning input on CyberKrea Sampler is intentionally left disconnected.The workflow already uses NegPiP, which merges the positive and negative prompt strings and converts the negative side into negative weights before sampling.So nothing is missing when the sampler's separate negative input is empty.You can still connect it manually if you want to experiment with traditional negative conditioning / sigma-window guidance.<hr />Krea 2 Turbo Enhancer IncludedComfyUI-Krea2T-Enhancer is wired directly between the model loader and the LoRA stack.It is included but disabled by default:<ul><li><code>enabled</code>: false</li><li><code>strength</code>: 0.3</li></ul>Enable it if you want to experiment with stronger prompt adherence.Leave it disabled for the normal CyberRealistic Krea 2 behaviour.The node is still considered experimental by its author.<hr />Face Detailer Now Runs Before UpscaleThe Face Detailer now works on the image at its original generation resolution.The corrected result is then passed into SeedVR2, allowing the upscale stage to carry the improved face forward instead of trying to repair an already-upscaled image.Both comparison nodes remain available so you can inspect:<ul><li>before / after Face Detailer</li><li>before / after Upscale</li></ul><hr />Save Node RenamedThe metadata saver is now:<code>CyberdeliaSaveImageWithMetaData</code>Make sure comfyui-cyberdelia-metadata is updated before loading the workflow.Older versions use the previous node name and may show the save node as missing/red.<hr /><h2 id="custom-nodes-used">Custom Nodes Used</h2>The full workflow references nine custom-node packs.The core generation workflow only uses part of this list.
