I ran into some issues with this video. I’m using Unity version 2020.3.25f1 which was the closest version I could find to the LTS version referenced in the beginning of the course. After importing the package provided in the resources tab the terrain textures were missing, and objects in the hierarchy do not match the video. It’s missing the rock, and ENVIRONMENT & ENTITIES objects. I think it might be out of date? Anyway, I fixed the textures by going into the terrain → Paint Texture inspector menu and replacing the layers that were missing with layers Unity found.
Also creating a prefab of the player rig and dropping it into this scene did not automatically set up the camera, looks like the scene in the video already has a cinemachine brain component on the main camera but the package I got didn’t. For anyone watching who might have that issue, just add a Cinemachine Brain component to the main camera and then the player rig will work properly.
