Run from the repository root with Vulkan SDK tools on PATH. Enable the optional asset_stylize module in your normal engine configuration. On Windows, the verified trimmed configuration was minimal plus asset_stylize, font and devtools (the latter two satisfy existing graphics/CLI link dependencies). Use the normal README dependency setup before configuring a fresh build.

The executable writes author/effect.eva, consumer/effect.evpack, and five engine-owned PNG captures. It exits nonzero if a behavioral check fails. The left sphere animates; the right retains its own weaker intensity and tint. failed-reload.png and reloaded.png must equal initial.png byte-for-byte. animated.png differs only on the left; stopped.png removes the left effect.

Author parameters in declaration order: phase is slot 0, strength slot 1. The probe authors a MeshVfx curve from phase 0 to 2 over a two-second cycle. To use this in a game, prepare a source candidate with prepareMeshVfxPackage, publish with the existing asset store and Cook pipeline, then load the cooked entrypoint with EvpackMeshVfx::load. Keep Graphics alive longer than the instance; call advance(dt) and draw inside your existing render lifecycle. The example selects additive transparent blending without depth writes.

For a standalone shader source asset, the CLI also supports:

eve asset import build/shader-demo/effect.json --from shader --package-id 018f6f22-2490-7ad2-bf58-4f1dbca31040 --name example.effect --out effect.eva
eve asset cook effect.eva --target windows-x86_64-vulkan --out effect.evpack
