When I open a project everything is pink ...

we are creating a project for our thesis.We use different laptops… I copy pasted the updated folder to my laptop but when I tried opening it on my unity it says “Selected Folder is not a unity project”.

the folders are:
Desktop\CAPSTONE v1.0\ASIA\CHINA
Desktop\CAPSTONE v1.0\bg
Desktop\CAPSTONE v1.0\OCENIA\AUSTRALIA

This is what I did… I created another folder inside CASPSTONE v1.0 and named it ‘Assets’ and moved other folders inside it. It finally worked… it finally opened… but everything is pink… what could be wrong?

Pink means that in MeshRenderer component some of the materials are corrupt (perhaps a shader problem)

Create a new material and assign it to Background. If you can, copy the assets from the previous computer and import them into this project (materials, etc) and use them here

Basically, you want to preserve the folder structure of the project from Computer 1 when transporting to Computer2.

You did this partially with renaming and moving folders.
