# Unreal Project Config

Use typed, project-scoped configuration edits instead of clicking Project
Settings or writing arbitrary files. The skill only touches the active
project's `Config/DefaultEngine.ini`, backs up the file before a change, and
reports when an editor restart is required.

Workflow: inspect -> apply an allowlisted setting or preset -> save/restart the
editor when required -> verify disk and runtime values with this skill plus the
official Unreal MCP CVar/log tools.

The first version intentionally scopes writes to renderer ConsoleVariables used
by the Manhattan showcase. Unsupported keys return an actionable error.
