I'm using Unity 2020.3.20f1. I created a 3D object (sphere) and applied a material which has a custom shader. Now the whole sphere appears pink.
I'm using URP, but I added it to an existing project. What I already tried is to upgrade the material to URP material, but it didn't fix it.
Thanks!
The problem was that I didn't add URP as the fefault shader in the graphic settings. (I had to manually create a URP renderer asset tho) After adding it and upgradeing ALL materials to URP it started working.
