Building a game with Opus 5.5 across Blender and Unreal Engine
A seven-step workflow uses Meshy for models, Blender for cleanup, and Unreal for levels and lighting, with Opus 5.5 coordinating all of them from one chat in about 4 hours for a first build.
here's how to build a game like this with Claude Opus 5.5 + Blender + Unreal Engine + Meshy... the trick is giving every tool one job, but there's a smart way to set it up: - step 1: install Claude Code, Unreal Engine 5 and Blender 5.1+, all free except the Claude plan - step 2: connect Blender through its MCP add-on, and Meshy through Meshy MCP with an API key - step 3: brainstorm 5 game ideas with Opus first, pick one, have it expand the idea before anything gets built - step 4: tell it your GPU, so it pushes the graphics as far as your machine can run - step 5: Meshy generates the props and characters, Opus imports them into Blender and cleans them up - step 6: Opus brings everything into Unreal: the level, lighting, HUD, minimap - step 7: play it, then add one feature per prompt: combat, enemies, quests who does what: > Meshy: the 3D models > Blender: cleanup, placement, materials > Unreal: lighting, physics, the actual game > Opus: runs all three from one chat and the real cost... one full first build took about 4 hours and ~19% of a weekly Max plan build the first level well, then the next ones go much faster because the assets already exist
