A few years ago someone posted this on Reddit claiming to have made this character in blender. I thought that was really fucking dumb because it would take less than an hour and it was clearly ai. They argued with me when I said as much, so I did it myself in about 30 minutes to prove a point.
The donut is a good one. It's like riding a bike I bet
3D software has changed a lot over the years, blender included. It can be pretty confusing until you get the hang of the hotkeys and navigation. Blender does a lot so finding your way around can be annoying and every action has a shortcut that you either have to already know or Google to find out lol. But you can change the key maps to match other software (like Maya) which might make it easier for you.
