I’m using BP_Splinemesh from Archviz sample (I’ve also tried to replicate BP from different YouTube videos). The problem is the editor doesn’t update the mesh in its viewport. Everytime I move a vertex of the spline, i have to wiggle it once more and then undo last move, to see how it affected the mesh. The problem only exists with the 5.4.1 version, while 5.3.2 works properly.
