The moments they call things glitches/bugs when it makes total sense that an object is placed there. EVERYTHING in 3d enviroments in videogames is smoke and mirrors. The way he explains things and is reacting to things he finds in the world shows that he has zero knowledge about design.

He once found a checkerboarded piece and noticed that he also spotted it in other games... Every single hobby creator out there knows that it's an Unreal Editor template with no textures.

I just wished that the creator took his time to learn more about game design before sharing information that is totally incorrect and only shares mis information about the design of 3d worlds and games in general. It really feels like they found a tool, came up with the idea for YT videos and started rolling right away, without any research.
