Every configurable option in OPAL.
OPAL’s settings are grouped into categories. Defaults are called out in bold — you don’t need to touch most of these.
Appearance
| Setting | Default | Notes |
|---|
| Theme | System | Light / Dark / System |
| Accent color | O3DE Blue | Affects buttons, highlights, progress bars |
| Density | Comfortable | Compact reduces paddings ~25% |
| Sidebar width | 240 px | Resize live by dragging the divider |
Storage locations
| Setting | Default | Notes |
|---|
| Engine install directory | ~/.opal/engines | Each engine gets a subfolder |
| Project workspace | ~/O3DEProjects | Default location for new projects |
| Gem storage directory | ~/.opal/gems | Shared across projects when possible |
| Repository cache | ~/.opal/cache/repos | Indexed gem repo metadata |
Changing a storage path prompts to migrate existing contents — you can opt out and leave the old contents in place.

Privacy
OPAL ships with telemetry
off. We don’t collect anything by default. If you opt in, we get crash reports and anonymous feature-use stats — nothing else. See the
Privacy page for the full breakdown.
Import / export
Advanced → Export config writes every setting to a JSON file you can back up or share with a teammate. Advanced → Import config reads it back.
