We’ve recently released two plugins for Substance Designer (2019.2 or above):
Global Search brings new search capabilities to Substance Designer, letting you search terms in various ways over multiple packages/graphs/functions as well as track a list of items left to work on or temporary ones to remove before production. This plugin is free, details on this page.
ParamCopy handles parameter copy and node state storing/recalling, these can be very helpful when working on a graph to test temporary combination of settings or demo them. Even though ParamCopy can be used for any graph, it is also especially useful with Hair & Fur to copy certain hair generation properties between instances as well as during the tiling of textures. See details on this page.
