SUBSTANCE MATERIALS BREAKING:
Substance materials that contain a custom output with a blank usage will break on import. Also, Substance materials containing duplicate usages will break.
Older sbsar files from GameTextures.com are not currently compatible with the Substance in Unity plugin. The GT materials that contain unsupported Usage outputs are breaking.
Before using the plugin, be sure to make a backup of your project.
Using the plugin with Unity 2019.2 will produce the following error:
InspectorSubstanceImporter.OnInspectorGUI must call ApplyRevertGUI to avoid unexpected behavior.
This error can be cleared and will not affect the functionality of the plugin
