Hey classmates using Mac. I ran into an issue trying to unzip the particle assets Rick provided and importing the package into Unity. I spent a long time looking through these discussions and rewatching only to find a solution on my own so I’m sharing in case I can save you time:
Originally when I unzipped the folder it created another folder called Impact VFX. Inside where three folders with gibberish names and contained some .meta and other random file types. None of these could be used in the project.
Searching in my Finder for the app which unzips compressed files (for me it is Archive Utility), I opened the app and at the top drop-down menu opened the Preferences (Archive Utility -> Preferences). Here I found a checkbox option which said “Keep expanding if possible”. Turn this OFF so that it doesn’t expand the .unitypackage file into its contents.
When I turned this preference off and unzipped the compressed file that Rick attached, it gave me a ImpactVFX.unitypackage file that I could import to my project and continue the lecture.
Hope this helps someone down the road. Keep up the good work everyone!
