- In the documentation examples we often use <L.> means Light scattering type with all scattering events. For light group AOVs, using <L.> is required instead in place of L. There's no functional difference.
- lpe:CD<L.> means camera with diffuse scattering event for light scattering type.
- lpe:CO means camera with emissive objection (since emissive does not need any light, there is no L).
