I’m not sure if this is a bug or was intended this way.
It took me about an hour to find the Get Velocity node. It seems really strange that right clicking in a Vim does not bring it up, especially since there are screen shots that say and show the most useful thing to do with a vim is to blend animations based on Velocity.
I finally found it by digging through an older post and saw that it was in the “pallete” menu.
It appears like two different tree views were developed, one for the right click and one for the palette window and the right click is not complete.
The right-click menu is context-sensitive. Same with the menu you get when dragging off a pin. If you just right-click, you only see things that work with the AnimBlueprint (Vim) itself. GetVelocity belongs to a different class (Pawn) so you have to drag off a pin the gives you a Pawn reference to get access to it. The Palette is there to give you access to everything because some people prefer to work that way instead.
It might make sense with more use. As a first time trying to make a vim using a blendspace it was just confusing. If I was a normal person I would have given up. I’m not normal though.
