Opus 5.5 builds an Unreal open-world combat prototype via MCP
Opus 5.5 connected to Unreal Engine through MCP generates terrain and foliage, adds sword attacks with Niagara trails, and makes grass burn where the blade hits.
build an open-world combat prototype in unreal engine with claude opus 5.5... in just a few days the trick is letting opus direct the work inside the engine. here’s the workflow: - step 1: connect opus 5.5 to unreal engine through mcp - step 2: generate the character in tripo ai with smart mesh p2 for a clean low-poly mesh - step 3: clean the asset up in blender, then import it into unreal - step 4: have opus build the map: terrain, hills, paths, autumn trees, flower meadows - step 5: add movement and sword attacks on top of unreal’s third person template - step 6: have opus add sword trails with niagara - step 7: make the grass react: it burns and darkens wherever the blade hits - step 8: run through the world and fix what looks off up close effects should touch the world. a sword trail is nice (dev: xikhar)
