Test data
golden/ and bgfx-reference/ contain historical reference screenshots. assets.list and assets-good.txt list asset samples; m2-numeric.json records Granny oracle comparisons.
Build the asset tools without a UI engine:
cmake -S . -B build-tools -DMT_BUILD_TOOLS=ON
cmake --build build-tools -j8
The active 40250 port tests run through script/port_gate.sh macos. The native SDL/Vulkan client has its own acceptance runner, script/native_mac_acceptance.mjs.
