Unity is being required to ditch Enlighten due to Geomerics shutting it down. While Unity will continue to support it through 2020 LTS, they are working diligently with a new group to produce a new lighting product by 2021.
Quote"Our Lighting team has been focused on making a robust solution to replace Enlighten baking over the last years as well as provide great alternatives for the fast workflow possible with real-time Enlighten pathway through improved baking. The CPU Progressive Lightmapper is production-ready. Our GPU-based Progressive Lightmapper is used widely now with a great set of features and is targeted to be production-ready in the 2020.1 release. We’re continuing to add improvements, focusing on highly-iterative workflows, with every release. For example, in Unity 2019.1, we’ve added NVIDIA® OptiX™-based AI denoising, which gives you perceptually noise-free lightmaps up to 10x faster than before and many other features targeted for easier, more intuitive workflows and faster iteration for artists," Unity said.
