Script-Only mode is a global toggle for people who aren’t compiling C++. When it’s on, OPAL keeps the interface focused on prebuilt engines and script-based work, and hides everything to do with building from source.
You can turn it on during the onboarding wizard or any time from Settings.
What it changes
While Script-Only mode is on:
- The Source platform filter is hidden on the Engine Downloads page.
- Build actions on source engines are hidden.
- Unbuilt source engines are marked unavailable, with a note explaining why.
- Source-related options are hidden in project gem configuration.
Turn it off again and all the source-build tooling comes back.
