Click - upgrade materials to HD >

Render pipeline is non existent in the project

What am i doing wrong?

This isn’t needed ^

and to create a Render Pipeline Asset - https://discussions.unity.com/t/687913 page-8#post-3411230

Ok thanks, i did that and everything went pink, started upgrading materials, some of them were fixed, however im still getting this error that stops upgrade process in the tracks

Not sure about that error but it will only update materials that used the Standard Shader (Or other default Unity shaders) to the new Standard Shader of the Pipeline you are using. Custom shaders/materials with custom shaders will have to be updated manually.
