  • Keep the entire Unity project folder on the same portable drive to avoid absolute-path issues.

  • Avoid hardcoding absolute SDK or toolchain paths inside project settings; prefer environment variables or project-specific settings files that can be updated per host.
  • If using Git or another VCS, consider cloning repo onto host drive and keep the Editor portable separately; alternatively, keep both Editor and project on the portable SSD.
