@react-three/lightmap

In-browser lightmap and ambient occlusion (AO map) baker for react-three-fiber and ThreeJS.

Example:

<Lightmap>
  <mesh position={[0, 0, 0]} castShadow receiveShadow>
    <boxBufferGeometry attach="geometry" args={[3, 3, 1]} />
    <meshStandardMaterial attach="material" color="#ff6080" />
  </mesh>

  <mesh position={[0, 0, 1.8]} castShadow receiveShadow>
    <boxBufferGeometry attach="geometry" args={[2, 2, 2]} />
    <meshStandardMaterial attach="material" color="#4080ff" />
  </mesh>
</Lightmap>

Try it in this editable sandbox.

NOTE: if you are using mode="legacy" on your <Canvas> tag please add legacySuspense flag to the lightmap, otherwise it will not wait until your scene content is fully loaded. This is not an issue in most situations, unless you have explicitly set the mode prop on <Canvas>.
