The Builds queue handles engine source builds and project builds. Like downloads, each build shows progress and can be managed while it runs — and its output is always a click away in the log viewer.
Per-item controls
- Pause / Resume an individual build.
- Cancel a build. Cancelling also stops the child build processes it spawned, so nothing is left running in the background.
- Move to Top or drag to reorder, with the same smart demote / no-victim notifications as the downloads queue.
- View Log streams the build’s output into the shared Logs viewer.
Whole-queue controls
- Clear Completed clears finished builds from the list.
Concurrency
Set max concurrent builds in Settings (default 1). O3DE builds are memory-hungry, so 1 is a sensible default on a laptop; workstations can run more. Build parallelism (thread count) is set separately in Build Tools settings.
