The material shown here started to be posted in the Summer 2020 version of the class, with tweaked material posted in later summer. It is being resused in the Summer 2024 offering, and will probably work in versions of Unity from 2019.4 up to 2022.3 (and hopefully later, but who knows). Some minor tweaking may be needed. Always be sure that the lighting is set to "Linear" and not "Gamma" in the "Player" settings.
GPU20IntroShaders.unitypackage corresponds to Lectures 16 through 24; GPU20EnvMapShaders.unitypackage corresponds to Lecture 25; GPU24ProjTexShaders.unitypackage corresponds to Lecture 27; GPU21PostProcDefRendBuiltInDIY.unitypackage corresponds to Lecture 32; and GPU21PostProcStackBuiltInRP.unitypackage corresponds to Lectures 33 and 34.
When trying out one of the unitypackages, start with a blank vanilla "3D" project, and drag the unitypackage onto the Assets folder. If it gives you a warning about a scene file changing on disk or something like that, don't worry about it, just click through the warning. The assets will then be loaded, but you won't see anything new in the scene; you need to go to the scene folder and double-click on one of the particular scenes to load it.
For the GPU21PostProcStackBuiltInRP package, you will FIRST want to install Post-Processing Stack (v2) from the Unity Package manager and THEN import the package. You can load them in the opposite order, but then you will also need to invoke "Reimport All" to get everything to work.
For the GPU22URPIntroShader package, you will want to start a blank URP project. Alternatively, you can start a standard built-in pipeline project, install the Universal RP from the Unity Package manager, import the the URPIntroShader package, then set the Scriptable Render Pipeline Asset in the Graphics tab of Project Settings to be the provided MyURPAsset.
