# Objective - Add support for loading lights from glTF 2.0 files ## Solution - This adds support for the KHR_punctual_lights extension which supports point, directional, and spot lights, though we don't yet support spot lights. - Inserting light bundles when creating scenes required registering some more light bundle component types.
