+  <div class="desc"><p>Turns on **soft shadows** for lights emitted after it. A hard shadow tests a single ray from the light centre to each pixel, so an <a href="light-occlude"><code>occluder</code></a> edge cuts sharply. With <code>radius > 0</code> the light is treated as a small disk of that radius: each pixel samples visibility from a cross of points across the disk and averages them, so the shadow edge fades through a **penumbra** instead of a hard line. <code>Light.soft(0)</code> restores hard, single-sample shadows. The setting persists until changed. Deterministic (fixed-point average of integer ray tests).</p></div>
