asset linking issue

Unity Engine
1

today has been a scene breaking day.

deleted the wrong scripts, no warning of scene dependencies and no undo to save the day
now the shaders, when I imported the unity built in shader folder inside, the list of shader doubled up as expected but the surprise came when i deleted the folder from the asset project - all the objects turned white – the built in shaders i imported overrode the linking to the unity shaders.
so is there a way to revert back to the unity shaders so i can clean up my already chaotic project?

No idea re an answer to your question, though I doubt it very much.

But… save new version of your projects often… esp before any type of deletion or culling/cleanup. It’s as easy as clicking on you project folder in finder and clicking CMD+D…saved my arse 1000 times over!

P.S. Make sure you DON’T have the project open in Unity when you do this as it will not duplicate a complete project.
