Here's the video "Armatures - Blender 2.80 Fundamentals"
The video narration says "you can download this character in the description down below"
The video description links to a blender cloud page with zipped assets:
But in the zip there is no unrigged model, only rigged ones. And the filenames don't make it easy to find the file containing the character. The rigged character (I think it's in the Sky file) can be edited to delete the armature of course, but it's off putting for beginners to need to do this without instruction.
I expected the zip to contain a blender file named something like "Unrigged character" with no rig (and no scarf), just like in the video.
