.github/workflows/v2-multiplatform-build.yml defines the parallel CI matrix for Linux, macOS, Windows, and WASM. The matrix is validated by V2/ue/Tools/check-v2-multiplatform-ci.py against V2/ue/Build/CI/v2-multiplatform-builds.json.

The matrix runs with fail-fast: false and max-parallel: 4 so one platform does not hide failures in another platform lane. Linux and macOS use UE_RUN_UAT BuildGraph targets from V2/ue/Build/Build.xml; Windows runs the Win64 shipping BuildGraph target; WASM installs wasm32-unknown-unknown, wasm32-wasip1, and wasm32-wasip2 before building v7-dev-hygiene with cargo build --release --locked.

Required gates:

  • multi-platform-ci-linux
  • multi-platform-ci-macos
  • multi-platform-ci-windows
  • multi-platform-ci-wasm
  • multi-platform-ci-parallelism

The primary parallelism metric is build.multiplatform.parallel_jobs. Build evidence is uploaded as per-platform artifacts named v2-multiplatform-linux, v2-multiplatform-macos, v2-multiplatform-windows, and v2-multiplatform-wasm.

The CI validator is:
