You get an uncluttered view without messy wire routing.</li><li>⚡ Integrated SeedVR2 Upscaler (ON / OFF Toggle): Includes a high-fidelity SeedVR2 upscaling pipeline ready to go. Turn it on for ultra-detailed high-res outputs or toggle it off for fast test iterations.</li><li>🎛️ Power LoRA Stacker: Driven by rgthree's Power LoRA Loader. Effortlessly stack, enable/disable, and tweak multiple LoRAs without rerouting a single wire.</li><li>📖 Built-In Cheat Sheets &amp; Guides: Never leave ComfyUI to look up settings! Interactive Markdown guides are embedded right next to the nodes, explaining:<ul><li>KSampler &amp; Resolution settings</li><li>LoRA stacking best practices</li><li>SeedVR2 Upscaler parameter cheat sheet</li><li>Portable installation &amp; node troubleshooting guide</li></ul></li><li>🏎️ NVIDIA Blackwell (RTX 50-Series) Ready: Includes a quick toggle fix for Blackwell hardware users, as well as standard PyTorch fallback guidance.<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/8bc4e2a4-48d5-4f00-8ea4-481ff1b51b52/original=true/8bc4e2a4-48d5-4f00-8ea4-481ff1b51b52.jpeg" /></li></ul><hr /><h3 id="workflow-breakdown">📦 Workflow Breakdown</h3><pre><code>┌────────────────┐ ┌────────────────┐ ┌──────────────────┐ ┌────────────────┐

Krea 2 Workflow v1.4 | Clean, Modular & Beginner-Friendly (with SeedVR2 Upscaler)

### 1.4.5 Added image ratio cheat sheet.### 🚀 What's New in Version 1.4 (v1.4.3 &amp; v1.4.4 Patch)Version 1.4.3 introduced a major structural overhaul focused on decluttering the canvas, integrating high-res upscaling, and adding built-in documentation directly inside ComfyUI.#### 🔧 v1.4.4 Patch Update* **Updated On-Canvas Manager Instructions**: Fixed and simplified the embedded Manager installation guide for ComfyUI Portable users. Clarified the rule for applying updates:* **Custom Nodes / Code**: Requires a **Full ComfyUI Restart + Browser Refresh <code>F5</code>)**.* **Models / LoRAs**: Requires **only a Menu Refresh** (no restart needed).---### 🌟 Major Features Introduced in v1.4.3#### 🧹 1. Complete "Zero-Spaghetti" Subgraph Refactoring* **Subgraph Architecture**: Consolidated the main workflow blocks (Model Pipeline, Prompt/KSampler, and SeedVR2 Engine) into clean ComfyUI Subgraphs.* **Cable Cleanup**: Eliminated hundreds of overlapping wire connections across the board using KJNodes Set/Get routing for a sleek, modern visual layout.#### ⚡ 2. Integrated SeedVR2 Upscaler Pipeline* **Built-in SeedVR2 Engine**: Added a full SeedVR2 upscaler setup natively in the workflow.* **Instant ON / OFF Toggle**: Easily toggle high-res upscaling on or off using fast group bypass switches (rgthree) without touching any wires.#### 📚 3. On-Canvas Cheat Sheets &amp; GuidesEmbedded floating Markdown documentation blocks directly onto the workspace so you never have to guess settings:* **ComfyUI Portable Installation Guide**: Updated step-by-step instructions for installing missing nodes via ComfyUI Manager.* **Model Panel Guide**: Clear breakdown of model types, text encoders, and VAE choices.* **LoRA Guide**: Rules for stacking multiple LoRAs effectively without quality degradation.* **SeedVR2 Upscaler Cheat Sheet**: Parameter guide explaining tile sizes, attention modes, and offloading.* **Prompt &amp; KSampler Settings**: Explanations for CFG, schedulers, denoise levels, and batch sizes.#### 🏎️ 4. Hardware Compatibility &amp; Performance Updates* **NVIDIA Blackwell (RTX 50-Series) Fix**: Included dedicated <code>BlackwellAttentionFix</code> logic with simple bypass instructions for 50-series card users.* **LoRA Stacking**: Integrated rgthree Power Lora Loader for hassle-free LoRA management.* **Optimized Krea 2 Defaults**: Pre-configured for <code>krea2_turbo_fp8_scaled</code> and <code>Krea2-Engineer-V1-bf16</code>.---💡 **Upgrading from an older version?**Make sure to run **ComfyUI Manager ➔ Install Missing Custom Nodes** after loading the workflow to auto-grab the required custom nodes (such as <code>seedvr2_videoupscaler</code> and <code>rgthree-comfy</code>). Remember to **restart ComfyUI and refresh your browser <code>F5</code>)** after installing new custom nodes!
