UnrealWeek in TD, Oct 18–24, 2026: Epic's AI game jam runs on Unreal MCP, where your docstring is the APIIn the week of Oct 18–24, 2026, Epic announced an AI MegaJam built around Unreal MCP, the editor's server for AI agents. We ran a small Python toolset through it in Unreal Engine 5.8.4 to see what a model reads: the whole docstring, a schema built from type hints, and arguments that are converted rather than checked.
UnrealLinting game assets: a 40-line Python script that audits normal maps in an Unreal projectUnreal's editor exposes every asset's typed settings to Python. A short linter finds normal maps stored with colour settings, fixes them through the editor's own property path, and fails a headless build when it finds one. Run in Unreal Engine 5.8.2.
