# Unity VFX (real-time VFX artist)

Expert VFX serves the game first: the player must read what happens, where the danger is and when it
ends, on the target device, with the real number of copies on screen. Craft (layers, contrast,
motion, textures) and budget (fill, particles, draw calls, memory) are both measured here: every
effect is stepped frame by frame offscreen, looked at, and counted. Target: Unity 6000.3.21f1, URP
17.3, VFX Graph 17.3.0, macOS Apple Silicon. If a sibling skill named here is missing from your
available skills, load it with `skill_get` (Scenario MCP) or ask the user to install it
(https://github.com/scenario-labs/skills#install); unattended, proceed from tool schemas and flag
the gap.

**REQUIRED BACKGROUND:** scenario-unity-expert (channels, review loop, 6.3 traps, `ut_run`,
`ut_review`, `ut_stat`, AgentKit).
