Description
[EXT_lights_image_based](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Vendor/EXT_lights_image_based/README.md) lets a glTF provide its own environment map and irradiance coefficients which can build right on top of our existing IBL work https://github.com/AnalyticalGraphicsInc/cesium/pull/7172
Contributor guide
Research direction
Review the EXT_lights_image_based README and the existing IBL work referenced in PR 7172. Done means Cesium supports a glTF-provided environment map and irradiance coefficients using that existing IBL foundation.
