When I create a spline through the Draw Splines Tool, I cannot draw any knots unless I switch to 3D mode. When I do that I get knots that are not oriented correctly or even in the correct positions.
After looking for a pathing tool for 2D I found 2D path, which is depreciated in newer versions of Unity.
That post specifically states to use the new splines package to replace 2D path.
This was really helpful!!! I couldn´t understand why the knots weren´t drawn in the scene, and I was like “omg should I recreate the project from scratch but this time with a 3D project to make it work?”. But then this reply and GIF helped me out. Thank you sm!!
