Hi everyone, Today we are announcing that after careful consideration, the built-in support for Substance materials will be deprecated in Unity 2018.1. To maintain compatibility, Allegorithmic is working on a new external importer, with plans to release it on the Asset Store for 2018.1. Unity R&D is on a mission to make the Unity editor as lightweight and modular as possible. Over time, this will allow us, our partners and Asset Store publishers to deploy updates for specific parts of Unity without having to launch an entire new version of the editor. It will also translate to a much smaller initial installation size for the editor, and greater freedom to choose exactly which additional features to subsequently install for your project. Deprecating built-in support for Substance materials fits well into this overall philosophy. We realize that this decision means a change in workflows for those of you who are using Substance materials in your projects, but Allegorithmic is continuing support in the form of three products for the Unity editor: An engine plugin that reads Substance .sbsar files (currently in development). A plugin that allows download of Substance .sbsar files directly from Allegorithmic’s Substance Source PBR material library. The live link with Substance Painter that allows immediate display of texture edits in the Unity editor. For projects in development that rely on the current Substance material support import functionality, you will of course have the option to continue to use Unity 2017.3 or earlier. We would very much like to hear from you if you have questions or comments.
