Quick answer: Tool changes (build pipeline updates, asset converter updates) introduce silent bugs. Specialized bashes after tool changes surface them.
Tool changes are invisible to gameplay testing. Specialized testing is required.
Smoke test asset pipeline
Re-import all assets; verify no regression.
Test build pipeline
Build for each platform; verify outputs.
Cross-machine validation
Same project; multiple machines; identical output expected.
Audit per change
Each tool change has a bash; verifies no regression.
“Tool changes ripple through asset pipelines. Specialized testing catches.”
If your studio updates tools regularly, the per-update bash is part of the workflow.
