Hey @concrescence,
I think this is in response to my comment. (Sorry new to commenting/responding on the forums) When I selected and extruded extra vertices, instead of the 2 that were shown in the video, then hit CTRL+J that’s when the deformation appeared. I didn’t even realize I selected additional vertices because my fin looked perfectly fine. It’s only when I joined everything I noticed the deformation. Not sure why that is once you hit join…
Sorry for the confusion on my original comment.
