Reimagining ArchViz Through AI
From legacy renderings to modern AI-enhanced visualization — a ComfyUI case study with Z-Image Turbo and Flux 2 Klein 9B.
By Roshan Abraham · ComfyUI · Z-Image Turbo + Flux 2 Klein 9B
01 · Overview
Project overview
A visual case study following a single archviz asset through a modern AI pipeline: from a decade-old legacy render, to a ChatGPT-redefined base image, through two ComfyUI 2× upscale branches, and finally to a mobile-friendly presentation output.
Legacy Render
Original image created over a decade ago
ChatGPT Redefined
Modern mood, lighting and material direction
ComfyUI Upscale
Two AI pipelines for 2× enhancement
Presentation Output
Mobile-friendly visual proof
02 · Baseline
Original render showcase
The legacy workflow has strong design intent but limited modern realism — flat lighting, simplified plants, softer edges and dated material response.
03 · Direction
ChatGPT redefined version
Before any upscale stage, ChatGPT reinterprets lighting, material and atmosphere. The facade gains richer material response, the vegetation feels grounded, and the whole scene becomes cinematic.
04 · Pipeline A
Z-Image Turbo result analysis
Tile-based 2× upscale with z-image-turbo_fp8_scaled_e5m2_KJ + qwen_3_4b + ae_zimage at 10 steps, denoise 0.22. Sharper details with strong preservation of architecture and mood.
05 · Pipeline B
Flux 2 Klein 9B result analysis
Same input, alternate refinement: flux-2-klein-9b-fp8 + qwen_3_8b_fp8mixed + flux2-vae at 20 steps, denoise 0.22. The result trades a little raw sharpness for cinematic coherence and a more unified global lighting feel.
06 · Comparison
Direct comparison grid
Same visual region. Four stages. Clear evolution.
07 · Pipeline
Workflow pipeline
From an old render to a publishable AI-enhanced archviz output.
08 · Takeaways
Technical insights
The practical value is workflow control.
Modernize legacy assets
Turn older renders into current visual standards.
Preserve architecture
Prompts explicitly protect layout, facade and materials.
Tile-based detail
2× upscale uses 768 px tiles with seam fixing.
Production advantage
More usable outputs from existing render libraries.
Visual storytelling
Atmosphere and material realism become presentation-ready.
Fast iteration
Two ComfyUI branches for comparison and tuning.
