+  <div class="desc"><p>Sets the **falloff curve** applied to every light emitted after it. A light's brightness ramps from full at the centre to zero at its radius; the ramp is raised to <code>exponent</code>, so <code>1</code> is the original linear falloff, <code>2</code> is quadratic (a softer, more concentrated core), <code>3</code> cubic, and so on. Like the occluder store, the setting persists across frames until changed — a game sets it once, or per light, and it rides alongside the short <a href="light-point"><code>Light.point</code></a> / <a href="light-spot"><code>Light.spot</code></a> signatures. Integer exponent, Q16.16 ramp — deterministic.</p></div>
