-#### Ignoring occlusion on some objects
+## Ignoring occlusion on some objects
 
 To disable the occlusion effect, simply add `userData={{ lensflare: 'no-occlusion' }}` to your object/mesh props.
 
-#### Improving performance
+## Improving performance
 
 Use bvh `<bvh><Scene></bvh>` to enhance the internal raycaster performance.
 
-#### Limitations
+## Limitations
 
 The Ultimate Lens Flare leverages the raycaster to examine the material type of objects and determine if they are `MeshTransmissionMaterial` or `MeshPhysicalMaterial`. It checks for the transmission parameter to identify glass-like materials. Therefore, for an object to behave like glass, its material should have either `transmission = 1` or `transparent = true` and `opacity = NUMBER`. The effect automatically interprets the opacity `NUMBER` value to determine the brightness of the flare.
