At 5:33 he rotates the snout as he finishes extruding it with the snake hook brush. Whenever I try that, it looks like this:
I guess I should have put the timestamp a few seconds earlier. You can see in my image that the initial chunk I extruded is facing the same way it used to, even though I used snake hook. In the video, the tip of the extrusion actually rotates to follow the brush.
williamatics Honestly it looks like your brush stroke is doing that "follow / leave behind" behavior...I can see the flow pattern in the topology.
Maybe you messed up some (Brush or other) settings. Try File > Defaults > Load Factory Settings.
