In this video, I’m breaking down my workflow to generate 100% consistent, 8-way isometric sprites for your games—without touching Photoshop. We aren't just generating random characters; we’re building a professional-grade asset pipeline using Nano Banana 2 and custom Codex skills to create sprites that actually match the legendary Final Fantasy Tactics aesthetic. 🛠️ THE STACK • Generation: Nano Banana 2 (Gemini 3 Flash Image) for high-fidelity character consistency. • Logic & Planning: GPT 1.5 and Claude 4.5 for prompt engineering and workflow automation. • Automation: Python-based "Game Dev Asset Tools" for automated flipping, stitching, and normalization. • Interface: Codex App & Codex CLI (within tmux) for managing the generation pipeline. • Transparency: Chroma Key Green strategy for clean background removal in sprite sheets. 🚀 WHAT YOU’LL LEARN • The Anchor Method: How to use a single reference image to "lock" character identity across all 8 isometric directions. • Cardinal vs. Diagonal: Why you should NEVER generate all 8 directions at once (and the 2-step fix). • Chroma Key Secrets: How to force AI models to respect flat backgrounds for easy sprite stripping. • Normalization Pipeline: Using custom scripts to ensure every frame has the correct height and foot-alignment for your game engine. • AI Walk Cycles: A sneak peek into using video-to-image generation to animate your static sprites into game-ready loops. 🕒 TIMESTAMPS 00:00 Intro 00:18 Asset Packs vs Custom 01:17 Resources and Tools 02:38 Step 1: Start With Reference Image 05:25 Step 2: GPT Image 1.5 vs Nano Banana 2 05:42 Step 3: Handling Transparency 06:40 Step 4a: Don't Generate All 8 Directions 07:36 Step 4b: Generate 4 Cardinal Directions (N, E, S, W) 08:31 Step 5: GenerateAnchor + Cardinals = Diagonals 09:34 Step 6: Extract frames and stitch 12:08 Bonus: Animate Walk Cycles using video generation 12:42 Demo: Full Walkthrough in Codex 14:41 Step 7: Normalize and Export 15:25 Wrap Up #vibecoding #aigamedev #isometric #nanobanana2 #pixelart #indiedev #finalfantasytactics #codex #gamedev #nanobananapro #vibecodegames
