How do you figure out which asset requires a plugin? (Substance)

With 4.9.1 I started seeing a popup that says I need Substance plugin and asks me if I want to install it. I haven’t used Substance in ages, and clicking no on the popup has no effect. The project loads and executes just fine.

The popup is annoying though, and I have no idea which asset might be causing it to occur. Any ideas?


You can remove this pop-up by open your project file in notepad, and remove substance from “plugins” section.
