Cesium for Unreal’s geospatial environment add trueSKY’s envieonment of sky will be great, however trueSKY is not a open source project. Hope study together.
While we haven’t worked extensively with TrueSKY, the latest Cesium for Unreal update now allows users to use alternative directional lights with the sky system. This should make it more compatible with TrueSKY. If there are specific features you’re hoping for regarding Cesium for Unreal and its compatibility with TrueSky, please let us know by creating an issue in the Github repository.
Thanks for using Cesium for Unreal!
