After creating a glow shader in Unity, following this tutorial, https://www.youtube.com/watch?v=3ALkvh3pJXQ&list=LLaf3bskj3HXKlcOW93L70Xg&index=2&t=272s, I created a sphere, created a material applied the material to the sphere and applied the shader to that material. After that my sphere turn pink, what could be the problem ?
I tried this solution :
"install Lightweight Pipeline from window/package manager
in project panel select : Create/Rendering/Lightweight Pipeline asset
Enter to : Edit/Project settings/Graphics Add the Lightweight Pipeline asset created before to Scriptable Render Pipeline settings"
But then all of my scene went pink, so I checked If I had render pipeline core package installed in my package manager and I can`t find it in my project packages or in All packages ? Can this be the problem or is there anything else I can do? I do have Lightweight RP and Shader Graph installed in my packages ... Thank you
