The ultimate multi-stage local upscaling automation engine for cartoon and digital art. Convert wide 1344x768 raw generations into crisp, print-ready 3840x2160 (4K UHD) illustrations with zero stretching, zero blurriness, and complete local execution control!

This repository is distributed under the SUPERKLOK LABS UNIFIED PUBLIC ASSET LICENSE v1.0:

100% Free for Commercial Use: You are fully permitted to use this workspace, upscale configurations, workflows, and automated scripts to generate commercial artwork.

Mandatory Credit: You must credit Superklok Labs by linking to or tagging one of our official handles (Twitter(X) or Instagram) whenever you publish content created or upscaled with this asset.

Unlike generic web upscalers tied to restrictive cloud platform fees, complex token economies, or strict non-commercial models, this entire pipeline gives you total local freedom.

Indie Game Developers: Effortlessly scale game assets, UI elements, and character concept illustrations locally up to crisp 4K textures without losing line-art fidelity.

Content Creators: Automate high-volume batch image upscaling directly inside your workspace using integrated native folder file lists.

IP Creators: Monetize your massive upscaled artwork prints and digital store assets with absolutely zero platform subscription overhead.

Intelligent Padding Calculations: Calculates precise structural pixel margins for raw horizontal inputs. Upscaling locks explicitly onto a highly optimized 1344x768 bounding zone, mathematically calculating and trimming off extra canvas edges before saving.

Dual-Stage Super-Resolution: Routes image layouts through an automated model loader utilizing RealESRGAN_x4plus_anime_6B to push graphics up into a sharp intermediate state before finalizing resolution.

Anatomy Correction Pass: Smoothly applies specialized FaceDetailer, HandDetailer, and FootDetailer pipelines onto the upscaled boundaries to fix generation anomalies without destroying illustration traits.

Automated 4K Center-Crop: Trims final proportional layout boundaries with a native post-processing crop node to automatically output standardized, pristine 16:9 3840x2160 files.

Lightning-Fast Local Stack: Custom-tailored to run alongside high-speed architectures like sdxl_lightning_8step.safetensors to complete intense multi-pass rendering cycles on a standard 16GB graphics card.

Premium Multi-Stage Upscaler Workflow: The complete production-ready ComfyUIupscaler.json canvas layout configuration.

Immediate Benchmark Assets: Built-in 1344x768 reference image sample packs featuring the gold-standard Sunny Chuxem model to immediately benchmark your rendering hardware speeds.

Proportional Crop Presets: Fully automated script paths pre-targeted to deliver clean, crisp print dimensions out of the box.

Built entirely for processing efficiency on local desktop hardware. Operating System: Windows PC.

Hardware: NVIDIA GPU (12GB VRAM minimum, 16GB+ recommended for dual-engine workflows).

VRAM Compression: Runs an optimized FP8 startup batch execution (--lowvram --fp8_e4m3fn-text-enc), saving over 40% in VRAM overhead.

100% Portable Port: Operates entirely offline without cloud subscription fees or restrictive corporate filtering.
